Hello @belemo
This really was a hard blow, wow, I don't even want to imagine that happening to me, although it's really not much that I have in Metamask, the reality is that whenever there is a loss, however much it is, it leaves a bad taste.
To tell you that you are going to get it back, would be sowing remote hopes. What is true is that you are not going to start from scratch, because you already have an experience in the online business with cryptocurrencies, and you already know the way, but it is very important to improve the security levels and always use the internet that is not public, it is one of the main sources of income for hackers.
