There's also some serious fraud allegations at the exchange level, and I think there may be some truth to the rumor that USDT is being printed to drive up the price of BTC.
While all of this is concerning, it's hard to believe that BTC will drop lower than 1-2k in a panic. I think the market value has been established on a psychological level. I think blockchain is going to be taught in ECON101 classes in a few years. And while I don't think BTC is the best cyptocurrency, I believe in the coming years its value will stabilize, transaction fees will get fixed, and it will be a great store of value. It will be especially valuable for those without access to good banking systems.
The other really big problem is liquidity/access. I live in NYC and my coinbase account was randomly locked a few months ago(good luck if this happens to you). Now the only way I can buy/sell bitcoin is at a cash ATM with an 8% fee, or buy.bitcoin.com with a 7.5% fee. Bitcoin doesn't solve the problems of those without access to good banking if it's impossible to reasonably buy. I think this will get better too, but it's definitely gotten worse recently.
In conclusion: I think there's a chance BTC could be worth less than it is now this time next year. I think in 2 years, the total market cap of cryptocurrencies will be significantly higher than it is today.
