The maximum, "not your keys not your coins" is true and help to ensure all your assets are controlled and monitored by you solely your person can access, move and spend them accordingly. Trusting third parts only in case you wanna exchange and don't send more than you wanna see swapped. That's a rule to avoid get played like what Robinhood made from 2018-2022 with people's assets.

But because they can't always do fishy things and not get caught a California court just ordered a fine or more than $3.9M for playing with people's trust and money after rug pull them all those years. They played with people but now will pay.

It's important to never leave cash that amounts more than you want to exchange in a centralized platform as there, the staff controls your coins and users don't have nothing on them. Those platforms are made to exchange assets not to store cash on them. Money is stored in a non custodial wallet that gives acesso to users anytime they want their assets.

No exchange is safe as anytime can be hacked and users lose all their coins, so keep in mind that when dealing with these platforms is important to only send to them amounts that want to see exchanged and withdraw it asap. Remember:

CONTENT IS KING!
