So we have seen Cryptocurrency hit with many huge scams, come under increased scrutiny and regulation, as well as being the subject of environmental concerns.
Life is full of scam. Life is a mix of black and white, good and bad. You can not have one and don't have another.
Scammers use everything in life to scam, if they can. Cryptocurrency and Bitcoin are just one of things they can use to scam.
Cryptocurrency or is it still a safe haven?
No perfect safe heaven in life. Don't look for it.
Everything has risk together with chance to get profit. You must have good risk-benefit management for your capital and you will be good. Good even if your investment turns to be a loss partially or a completely loss.
