I have bad experience with bitcoin because I lost my money in HYIP and even in gambling but I forget the negative and I look for the positive things to happen into my life.
If you have lost in HYIP and gambling then that was your own mistake and you cannot blame or hate bitcoin for that, you should focus on positive sides of bitcoin and not negative.
funny thing is that when people lose money with gambling when they use their fiat currency, then they don't blame fiat, but themselves or the casino instead. but with bitcoin, they hate it. that's something i find very weird.
Very rightly said, people are loosing even the investment made with fiat, but they forget everything and move ahead but with bitcoin they share different perception and starts blaming it if anything goes wrong.
