Money is not at all safe in cryptocurrency, There are so many hackers around here who's only business is hack a wallet of bounty hunters to get money without doing anything.
Our money in cryptocurrency is not safe at all, because it is so risky to invest in crypto. Also, our wallets is not also safe and secured. But if you have an hardwallet or offline wallet, it will be safe for the hackers out there.
Just use cold wallets with or keys in your head or in a right place. Blockchain is one of the most secure places, so don't worry about it can be hacked or other troubles.
