To put what's in the article in a nutshell: 1) Cryptocurrencies are unlikely to replace fiat currencies, simply because governments would not want them to. Why would gov want to give up their money-printing rights and agendas? 2) They are prone to facing regulatory challenges as what are happening now. Yes, now and in the near future. 3) They are prone to scalability issues and volatility. Just look at those new regulations coming into place in some of the European countries as well as Korea (where even grannies and grandpas speculate cryptos). And it seemed not very difficult for governments to issue ban on cryptocurrencies either, for good reasons. Biden's recent tax hike proposal will also have an impact on both crypto and stocks markets (crypto gains are taxable in the US). (Hot fiat moving to fund crypto economy? Hmm... better to take some back.) What does it mean for bitcoin?...
