All investments involve risk. But people cannot insure themselves against this. Most often people are ruining greed. Fraudsters take advantage of human greed. You cannot trust a man who offers you a too favorable conditions. Use only proven resources and the risk of losing money is minimal.

The most important thing is never to put all your eggs in one basket. For bitcoin, I'd say its volatility is the huge risk that comes with it as the value is determined by its demand and supply and any little shit in the market won't be nice but all thesame,

I have great trust in bitcoin and I believe it will always thrive as it always has.
