I just remembered the poly network heist, one of the biggest heist in the history.
Is there also a possibility BTC can be hacked?
If it is, I bet every currency will start to declined.
How safety BTC security for you?
Want to know veterans answers.

Polygon is new currency but bitcoin is world first crypto-currency. It has been on the market for about 13 years. And there are tens of thousands of hacker teams trying to attack on it but they have never been able to hack it. And they couldn't figure out who made it. then why you think bitcoin can hack like Polygon..? it is not possible to hack Bitcoin.
