Just ignore the people who keep saying negative about bitcoin, that's what I am doing. Just ignore them, they are just a distraction. I said to myself that one day, you'll be needing my help even you turned me down in the past. I have so many debts last year snd I paid them one by one because of my income in bitcoin and bounties. Then, those who rejected me, to lend money, Godbless them. I have more money than they have right now.
People are very different. Many can soldiers at between is something bad and you can on the lost your money. But still there are many people who burn using bitcoin and give nice feedback for it.
