I mean trading is basically that isnt it? Gambling on BTC price? You could trade Options and futures to make it more in line with gambling nature. It was a great time to buy calls for ETH and BTC this month. especially ETH. Could do the same with alts as well.
It's different from what we are discussing here as they don't fall into the gambling category although when you are investing you gamble on the risk. What we are discussing is the fees now while gambling, the high fees have affected most of us especially the micro gamblers, not the other way around.
