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.
I have personally switched to Fiat to the most parts of gambling. Apologize for only reading the last bits of the page. I was gambling in ETH few months ago but now I just HODL and switched to fiat for the time being. The amount of time it takes to deposit BTC has risen considerably as well as the fees. Not attractive anymore.
