Welcome Litecoin Founder Charlie Lee.
All right. Let’s begin.I have been following your twitter for years. I found that you are quite a low key these days. The latest tweet is about BSV being delisted. Do you believe Binance is really doing the right thing?
Charlie Lee ：是的，我在推特上不是很活跃。因为我发现在推特上来回聊天会分散注意力，对我没有多大用处。另外推特上有太多愤青和容易抱怨的人。
Yes, I’ve been less active on Twitter. I found that a lot of the chatting back and forth on Twitter is distracting from real work and not that useful. Too many trolls and haters on Twitter.
I think Binance should not have listed BSV in the first place. BSV is a fully centralized coins and CSW is constantly attacking Bitcoin and even Bitcoin Cash. So I think it’s the right move to delist BSV to send amessage. It’s not ok to start suing Bitcoin users.
Plus their plan to patent things and suing people with patents is just not cool.
CSW is the total opposite of what everyone’s idea of how Satoshi would act, so I don’t know why so many people believe him to be Satoshi.
You were active in the bitcoin scaling debate. Now as both small and big blockers get their way. Do you think bitcoin still face the scalability problem?
Charlie Lee ：其实，很不幸，辩论还在继续。Roger等人仍然在不断“攻击”比特币，声称比特币现金是真正的比特币。所以现在有两种，但仍然有很多反对的声音。我认为比特币的扩容挑战会一直存在。去中心化和扩容始终是一个tradeoff（如一方达成，则另一方无法实现）。因为从定义上看，去中心化是低效率的，而低效率很难实现扩容。所以我认为Lightning不仅能维持去中心化还能帮助比特币扩大规模。对于比特币现金，在链上扩张最终将导致去中心化功能消失。所以，我们要像Lightning一样努力找出既能维持去中心化又能实现扩容的解决方案。
Unfortunately the debate has not gone away. People like Rogerare still constantly “attacking” Bitcoin by claiming Bitcoin Cash is the real Bitcoin. So there’s still a lot of animosity even though there are 2coins now. I do think Bitcoin will always have a scalability problem. Decentralization and scalability is always a tradeoff. Because decentralization is by definition inefficient. And inefficiency is hard to scale. I think Lightning will help Bitcoin scale without sacrificing decentralization. Whereas with Bitcoin Cash, scaling on chain will eventually kill decentralization. There’s still a lot of work to be done on layer 2 solutions like Lightning.
I remember that you and Roger had a bet about lightning network.
Charlie Lee ：是的。打赌的内容是18个月内闪电网络（lightning network）的商户是否能够超过1000家。我想Roger已经输了，因为CoinGate表示要为闪电网络提供4000家商户。
Yes, the bet was that there will be 1000 merchant accepting LN withing 18 months. I think Roger already lost because CoinGate supports LN for more than 4000 of their merchants.
Cindy ：匿名币Grin现在很火，对此，有人说匿名币有可能沦为最佳的犯罪工具。想请问您怎么看待匿名币？匿名币除了匿名，您还关注哪些技术特征？ The anonymous coin Grin is a real hit. Some say anonymity serves as a perfectcriminal tool. I’d like to know your thoughts about anonymous coins. Besides anonymity, what are the other technical features you focusing on?
Charlie Lee ：比特币和莱特币中都缺少的是可替代性（Fungibility）。可替代性是指所有代币与其他代币完全一致相同的概念。 所以接受代币的人无法区别对待收到代币的种类。但比特币和莱特币不适用于这种情况，因为这两种代币可追踪。因此，如果检测到用户在暗网市场中存放了他们的代币，Coinbase就可以禁止这些用户。
Fungibility is the only property of good money that is missing in Bitcoin and Litecoin. Fungibility is the concept that ever coin is identical from every other coin. So you can’t discrimate against the coins you received. This is not the case with Bitcoin/Litecoin because you can track their history. So Coinbase can ban a user if it detects that the user deposited their coins from a darknet marketplace.
This is not good money when there’s no fungibility. To get fungibility, you need privacy. So they go hand in hand. I think privacy/anonymity is extremely important for money. And that is why I’m working on adding MimbleWimble (the technology in Grin) to Litecoin. That’s something we are focused on this year. We will of course still keep up to date with all Bitcoin technology improvements.
So if mimblewimble were successfully added in LTC, do you think it will be added in Bitcoin?
Charlie Lee ：这个不知道，还得看看。但是我相信比特币未来的可替代性会更强。目前开发者们为了提高比特币的可替代性正不遗余力做各种努力。
That I don’t know. We will see. But I do believe Bitcoin willbecome more and more fungible in the future. Developers will work on fungibility improvements for Bitcoin.
Cindy ：比特币的价格超过了4200美元，这可能意味着它已经触底反弹。BCH也表现良好。莱特币进行奖励减半后表现会如何？现在是买莱特币的好时候吗？Bitcoin’sprice overcame the $4200 resistance mark, which might mean it already bottomed out. BCH also performed well. What will Litecoin look like as it is to implement reward halving?Is it a good time to buy LTC?
Charlie Lee ：没人能预测走势。但减半是上半年莱特币价格上涨的原因，或许减半前还会有行情，但我不能肯定。所以我总是提醒大家买和卖时都要考虑自己的成本。
No one really knows what the price will do. The reward halving might be why LTC is doing so well price-wise in 2019. Maybe the price will go up more before the halving, or people might take profit. It’s hard to say. I always tell people to average cost in when buying and average cost out when selling.
The news that Litecoin Foundation partnered with Ultimate Fighting Championship(UFC) is very eye-catching. Would you please tell us more details about it? Like who made this partnership possible, etc? Are there official members of theLitecoin team working on the marketing and promotion job?
Charlie Lee ：合作是临时达成的。我们的社区经理IlirGashi在UFC的母公司上班。他认为有合作机会就把我们介绍给了UFC。我们认为这是一个增加莱特币曝光率的好机会。再者，UFC等全球性品牌与我们合作，这本身就是对外释放的一个非常积极的、非常强有力的信号。实际上，他们在选择合作伙伴时非常慎重、挑剔。Litecoin Foundation的项目总监DavidSchwartz是负责项目筛选工作负责人之一。还有很多志愿者也帮助了我们。
The partnership was a last minute thing. Our community manager, Ilir Gashi, worksfor UFC’s parent company. And he saw the opportunity and introduced us to the UFC. We thought it was a good way to give Litecoin more exposure. And also it’s a strong statement that a global brand like UFC would work with us. They arevery picky in terms of what brands that are willing to partner with. Litecoin Foundation’s Director of Projects, David Schwartz, is the one working on allthese projects. We also have many great volunteers that help us a lot.
The parternership definitely give LTC more exposure and give investors more confidence. Thanks, Charlie, for all of your detailed explanation. Now it’s Blair’s turn to ask you another six questions.
The crypto space is full of new terms concerning fundraising. First ICOs, now IEOs. What’s your stance towards IEOs?
Charlie Lee ：基本上，IEO是由交易所审查的ICO，直接在交易所上线。因此，IEO的质量更高，更迅速且流动性强。所以从投资者的角度看，IEO肯定比ICO好。 这也意味着项目方必须要足够优秀才能被交易所选为进行IEO的对象。这种模式对所有人都是有益的。当然，IEO也有缺点，唯一的缺点就是IEO和ICO适用于完全相同的监管机制。所以，如果监管机构开始打击ICO，IEO同样会受到打击。不过这只是我的猜测。
IEOs are basically ICOs that are vetted by the exchange and will be listed on the exchange. So they are higher quality and will have immediate, or near immediate, liquidity. So from an investor’s point of view, IEOs are definitely better than ICOs. This also means that projects need to up their game to be good enough to be selected by the exchanges for IEO. So that’s good for everyone. The only downside with IEOs is that regulation will likely treat them no different than ICOs. When regulators start cracking down on ICOs, they will likely crack down on IEOs. But that’s just my guess.
So you support ICOs or IEOs be regulated?
IEOs are definitely better than ICOs, Traders should choose the trustworthy exchange to join the IEO.
Charlie Lee ：为了消费者资产安全，我认为需要监管，当然这是我的观点。
I think for consumer protection, they should be regulated. But I have no influence on that at all.
Ethereum is switching to the POS mechanism. Do you see a future in it?
Charlie Lee ：POS和POW是两种完全不同的共识机制。我认为它们都有自己的市场空间。 对于去中心化的货币来说，我认为POW更好。但对智能合约而言，POS可能是更好的选择。但是不容置疑，这两种机制都有各自亟待解决的问题。我很期待以太坊转向POS机制后会带来怎样的影响。
POS and POW are totally different consensus systems. I think they both have a place. For decentralized money/currency, I think POW is better. For smart contracts, POS might be perfectly fine. But there are definitely a lot of issues they need to work out. I’m looking forward to see what Ethereum does with POS.
Bitcoin’s block reward will halve in 2020. Most people argue that mining would beprofitable only when bitcoin’s price remains at an insanely high level. If bitcoin’s price is no longer attractive to miners, any chances that bitcoin developers will change the consensus mechanism of bitcoin?
Charlie Lee ：我并不认同挖矿需要价格好这个逻辑。无论比特币价格处是多少，挖矿都可以进行。挖矿其实是一种纳什均衡：如果价格低，部分矿工出局，停止挖矿。 这样挖矿难度就会下降，其余矿工可盈利。基于该理论，我并不担心比特币价格走低。另外，我认为比特币开发者不会改变比特币算法（共识机制），即使他们这样做，用户也不会同意的。控制权在用户手上，不是开发者，也不是矿工。
I don’t agree about mining needs bitcoin price to be high. Mining works at any Bitcoin price. Mining is a nash equilibrium. If price is low, some miners arepriced out and they stop mining. Difficulty falls and the rest of the minersare profitable again. So I’m not worried about a low price. I don’t think the bitcoin developers will change the consensus mechanism and even if they do,users may not follow. In the end, the users are in control, not the developersand not even the miners are in control.
That’s the spirit of decentralization!
Do you think it’s like revolutionizing themselves for crypto exchanges to work ondecentralized exchanges? What are problems with current centralized exchanges?
Charlie Lee ：去中心化交易所有两部分。一是交易所平台的去中心化，二是无监护（non-custodial）交易所。币安等加密货币交易所正在努力成为无监护的去中心化交易所。这些交易所其实并不是真正意义上的去中心化交易所。因为在真正的去中心化交易所上，上币和交易都不需要获取任何人的批准。但是问题是完全去中心化的交易所效率非常低下，这就是一个tradeoff。从业绩角度分析，去中心化交易所完全不是中心化交易所的竞争对手。但对交易所而言，业绩又是至关重要、不容忽视的。所以我不确定不久的将来会不会出现真正意义上的去中心化交易所。再说到无监护交易所，币安和Coinbase正在努力实现它。我们都知道，保障客户的资金安全并非易事，这其实就对交易所构成了一种潜在的威胁，因为如果一旦遭遇黑客入侵，交易所就会面临灭顶之灾。
There are 2 aspects of decentralization of exchanges. There’s the decentralization of the exchange platform and there’s the non-custodial aspect of it. Currentcrypto exchanges like Binance are working on “decentralized”exchanges that are non-custodial. These aren’t true decentralized exchanges. With true decentralized exchanges, you don’t need to ask anyone for permissionto list a coin or trade a coin. The probelm with true decentralized exchangesis that they are inefficient. It’s a tradeoff. A decentralized exchange couldnever compete with a centralized exchange in terms of performance, and performance is critical for traders. So I’m not sure if we will see a successful truly decentralized exchange anytime soon. As for non-custodialexchanges, it makes sense for companies like Binance and Coinbase to be working on them. Holding customer’s funds is hard and it present an existential threatto the exchange because if they get hacked it could kill the company.
You travel a lot. Do you feel any differences between the western and the eastern crypto communities?
Charlie Lee ：西方人认为加密货币是金钱、货币，而亚洲人认为加密货币是赚钱的一种方式。
Westerners see cryptocurrencies as money and Asians see cryptocurrencies as a way to make money.
Nothing wrong with that. Asians are good at making money, but we are also gamblers at heart.
Do you have any good advice for females in this industry? Or any suggestions to our 499Block Blockchain Community?
Charlie Lee ：女性和男性没有什么不同。你应该要找到自己的长处，想明白如何在本行业发挥自己的长处，做好真正的自己。作为一个社群，我认为你应该发出一些声音，让人们知道这个行业中有你们这么多女性在。我很高兴看到这一点。
Females are no different than males. You need to figure out what you’re good at and how you can apply yourself in this industry. As a community, I think you should make some noise and let people know there are so many females in this industry. I’m happy to see that.
