Statements from this episode (14)
Lee: Bitcoin needs consumer-friendly usability over self-custody to succeed
“I think that for Bitcoin to succeed, it has to be easy to use, right? You can't expect everyone to be able to store their own Bitcoins in their own computer or paper wallet and be able to secure it.”
Lee: Litecoin has four times the block space of Bitcoin
“It has four times the block space. So right now it scales better than Bitcoin and transactions are faster.”
Lee: Bitcoin will be store of value while Litecoin handles payments
“Pretty much, Bitcoin is going to be the best store of value, and Litecoin being faster, more nimble, will be, and also have cheaper fees, will be better used for transactions as a payment method.”
Lee: Ethereum will run into major scalability problems
“So I think in the future, Ethereum will really run into a lot of scalability issues.”
Lee: Lack of central adjudicators makes crypto forks highly unpredictable
“There isn't one. That's why the forks are so unpredictable, and you never know when consensus gets formed where a fork will actually happen.”
Lee: Dissatisfied crypto users prefer joining other tokens over forking
“Like, Litecoin hasn't experienced any kind of pressure to fork. I think there are so many other cryptos out there, so if you disagree with the direction of a crypto, it's always easier for you to just join another crypto community.”
Lee: Litecoin activated SegWit months ahead of Bitcoin in 2017
“So, for example, Litecoin was able to activate SegWit back in April, May of this year, whereas it took to August before Bitcoin activated SegWit.”
Lee: Bitcoin Cash miners forfeited $300K daily for ideological reasons
“A miner or a group of miners is leaving 300,000 dollars on the table every day because they're mining BCH instead of BTC.”
Lee: Cryptocurrency Miners Care Only About Profit, Not Loyalty
“Most miners, all they care about is making money. So, and that's fine, and that's how Bitcoin works. If all they care about making money, then they don't, they have no loyalty to any particular cryptocurrency.”
Lee: Transaction usability will matter more than community strength long-term
“I think in the future, that will be the same for cryptocurrencies, where in the long term, the community doesn't matter as much. It's more about just easy being able to easily use that currency.”
Lee predicts an imminent, massive crash in the ICO market
“So I fear that there's going to be a huge crash in the whole ICO market sometime soon.”
Lee: ICO crash will trigger capital flight to Bitcoin and Litecoin
“I think there will be a slight to quality. So people would Sell their tokens for Ether, and potentially sell their Ether for Bitcoin. So, it would crash a lot of the ICO tokens, a lot of the altcoins, but I think it would be good for the stronger currencies ou…”
Lee: Whole-coin misconception led retail investors to buy Litecoin over Bitcoin
“Biggest misconception, I guess it would be that people would think, You have to buy one whole Bitcoin or one whole Litecoin. People then realize you can actually buy, like, a small portion of a Bitcoin. I guess that helped Litecoin in some sense, where people …”
Lee: Bitcoin will replace fiat as the global reserve currency
“I guess I believe that cryptocurrency will take over fiat currency and become, like, the reserve currency, or Bitcoin could become, will become the reserve currency of the world, where everyone would Base everything on cryptocurrency. This is something that I …”
