TheMoonCarl is just a wannabe click-bait slut. Alessio is somewhat decent, but is an overly conservative trader who sees risks everywhere, regardless of how bullish or bearish the market is.
I somewhat follow multiple of these technical analysis youtubers to measure their sentiment and potentially trade against them if there is an interesting enough set-up. Carl was overly bearish before we had the run to $14,000 not that long ago, and that for quite a long period of time. The moment youtubers like him started to get bullish, the price went the other way.
I do however genuinely enjoy
Krown's Crypto Cave. I don't always agree with his analysis, but he's at least someone who understands how technical analysis works, which can't be said about many other youtubers, and he brings a dose of fun to the table that cracks me up all the time.
