Well I suppose the market went down 80% in the last year for other reasons - why aren't more people saying cryptos are zero sum games too? Many people have said cryptos are ponzis…. there is nothing backing the price in almost all cases and even if a company that issues the token becomes successful there is no actual reason for the token to gain in value if they don't share any profits (at least with stocks there is a possibility of a takeover and a real reason for the price to go up since they actually do represent ownership of the company and carry over to the new buyers unlike cryptos that do not represent anything, really). So best to treat it all as some weird game. The funny thing with BCC was that the price did go up (for the same reason any other crypto will go up if nothing backs the price) and went up higher than the amount of interest they paid, so their lending section was profitable and less of a ponzi than other cryptos. That was definitely the case for their lending and they definitely were profitable while they were running but I can't be bothered explaining again.
