Is is even smart to invest in bitcoin

This is why people losing their money.. Why? Because they asking about that. Of course it's not too good invest in crypto, but you can be lucky one. I lose my 550 litecoin on roulette 3 months before grow in 2017 and I was idiot because I lose like 250k$ on roulette so..

If you asking if it's smart to invest or not then don't invest is not for you
