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.
I cannot say our money here in this business is safe that is why if I earn I will get my capital and invest the rest so my capital will be safe and my earnings are in the investment. I will not keep all my money here because there is big chance of losing like if I can forget the password or the private key and most of all it can be hacked.
