So this is my take on crypto. Crypto is like the dot com era right now and when that bubble crashed there were certain one's that that were legitimate companies and they survived. Bitcoin will be destroyed cause it's a type of money and that won't be needed when QFS comes into play but other crypto's with good use case behind them like xlm and others will survive but they will get crushed when bitcoin get's destroyed and the whole crypto market has to be rebuilt and regulated like the stock market.
