It's certainly not as profitable as it was last year. I do know a few people that have made money this year by trading but they have mostly had a Bear Market mentality.
Last year if you threw money at a coin, you could have been resting assured that it was going to go up. This year has been such a roller coaster that I certainly wouldn't call it profitable as a venture to trade cryptocurrencies.
Some I know have made money, but most have lost quite a bit.
