I wasn't aware there were such things, but I agree with you about the above.  I'm not sure if we're starting another huge bull market or not, but bitcoin and altcoins are both up quite a bit compared to where the market's been the past two years. 

I don't know what crypto hedge funds do exactly (aside from holding/trading coins), but starting one now might be a bad idea but if someone had started one in 2018-19 they might be poised to make some decent money.  Not sure how many people would have had the intestinal fortitude to do so after everything looked dead for a long time--especially the altcoin market.
