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 really isn't safe be it in fiat or cryptocurrency form. In any forms, it can be robbed from us. They just differ in ways but with the same kind of persons: criminals. In fiat, it can be robbed from us by pickpockets and in crypto it can be robbed from us by hackers. The world is scary as it is and it is up to us how we can put our valuables into safety and away from those bastards who have nothing in mind but to get rich the easy way.
