In these almost three years watching crypto, I learned 3 things.

1) Crypto is the manipulation of whales

2) Cryptos are not as decentralized as they say; just one bad political or economic news from an important country like the USA and they drop

3) It doesn't help to have multiple coins, because you won't be able to study them all, and as a result, you end up making mistakes when trading them.

It's a bonus; a YouTube guy knows nothing, they said that in February or March the cryptos would explode, and so far it's only been a decline.
