I put all my btc in coinbase, is it safe?
This is an example of too much confident on storing all of his bitcoin in only one exchange. If you are a holder, try to explore those exchanges or wallets which are really safe in storing your assets and you will not have any fear of getting hacked. You always need to have a plan B or other wallets or exchange where you can hold your bitcoin so that you can still secure your assets when something bad happens on your bitcoin.
"Do not put all your eggs in one basket", they said.
But still, Coinbase is good because it has a lot of users, but Binance is really what I'm using for 2 years.
Coinbase isn't good because it often changes its TOS and you have to keep track of what they're doing all the time. Their support takes their sweet time to answer questions and as all other exchanges they don't like to take responsibility for anything.
Never hold coins on a centralized exchange! Use it if you have to trade but when you don't trade move to a wallet. It takes maybe 5 min of your time to set up a withdrawal.
That phrase about eggs in one basket is abused so much, especially in the altcoin section
