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 think that everything depends on how much a person cares about the safety, everyone has a choice, you can store your money so that it will be impossible to steal them, and you can click to the links in your mail and enter your private keys there, it seems to me that in 99% cases people themselves are to blame for their stolen funds.
Yes, safety and security of our assets is truely starts by every holders to minimize the online hackers advantage of stealing, as for me our money in crypto is safe as long as we always take care of it so always have a defensive move on the online world.
