TLDR; you can't explain the fluctuations.
I definitely agree. But look at Shiba, Dogecoin and GameStop for a minute. See what NFT's did. With enough sheep, you can move a freaking mountain. Apparently even if it's made of crap.
There are hundreds of these "mountains" waiting to be moved, but they never do. Only one lucky achieves it once in a while for a non-correlated reason. You can't know what the hell is gonna catch your fishing rod, but you should definitely not expect to catch a big fish. Pretty much the opposite; if you invest in the next dog coin, be prepared to even lose your boat.
I don't know what a trader should do, but if I did the job, I honestly wouldn't get involved with cryptocurrencies at all. I presume trading requires low risk orders, which will increase your income if you do it for a living.
