Hi,
Every exchange adding a new btc, eth, token address on the exchange website.
I think they need some private key to set the transaction on this websites.
So is this private key stored in a normal database?
And is this safe?
Exchanges are never 100% safe. I only keep certain amount of coins which i want to trade with and keep the rest in hardware wallet.
Although old and good changes are less likely to scam but we can't ignore this fact that anything can happen and should perform the security measures to safe our coins.
It is safe to do the exchange or the site itself.
just remember to keep your password safe and make a 2 authentication on your account for better security.
but please dont leave you coins or token there for too long as it is safer to be on a wallet.
exchange is just for changing your token to bitcoin or eth and not a wallet.
