I might be asking a silly question, but I'm learning about crypto and this doubt came up:

Everyone says that cryptos are decentralized...

But I saw that in many projects, few wallets hold the majority of the tokens.

And I also read that Binance or large companies have a lot of control.

So, how decentralized is all of this really?

If someone can explain it to me as if I were 5 years old, I would appreciate it.
