Here's the thing, if you are John and start to gamble, would you bet with high risk (betting with huge amount, betting in low chance of winning, etc)?
Betting in huge amount with high risk is like giving away your money because the chance to win is low and we know gambling is more on luck, you cant recover your losses if its your way to gain it back.
I'd rather hold my bitcoins and wait for the bull run, we know how btc perform we might be in bearish trend now but the time will come the price will recover. Just hold because you wont lose anything unless you already sell.
