I don't think Bitcoin is a bubble or a scam and most business individuals says that because of the huge price drop in Bitcoin but that is due to Countries tried making restrictions against Bitcoin and that is why BItcoin crashed and some tried to ban and with the price fall many thought Bitcoin will disappeared but now it is recovering like it didn't even care what happened and soon it will gain it's previous price very easily without any problem and anyone can see evidence with the price because considering last several months it is getting stronger day by day
