bitcoin always dangerous. just like a bubble. but I think bitcoin is a perfect tool to transfer money around the world without tax and high fee like paypal. but we dont have many people see that. they just buy and sell bitcoin by their emotion, by news. that's very very dangerous so I'm never all in when trading. just like poker
But the one who wants huge returns then he need to take that kind of risks,as you said the bitcoin investment is risky but until now bitcoin price keeps increasing in long term so hopefully it will continue in the future too,so I think it is good to go invest all our savings money (the money you keep it in banks without any purpose) into the crypto field.
