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.
if you are concern about the security of your crypto, always have them in desktop wallet or paper wallet. this way, only you have access to the private keys of your wallet. installing metamask also helps protect you from hackers as it will report all phishing and reported websites before letting you in. make it a point not to give out your private keys to anyone. also, for web-based accounts, use 2fa whenever possible.
