When the price rises sharply, it will attract people's attention. Similarly, when the bubble bursts, it can also attract people's interest. Those who have been belittle the bitcoin before can come out and claim that "the one that I said before is correct, those who buy bitcoin are idiots."
People laughed when man discovered aeroplane, internet, mobile phone etc. The same people are laughing now at Bitcoin, you are from the same breed. Do you know the nature of trading? If you are not interested then you can leave from this forum, do not try to make others fool here. Remember one thing those who Invested before few years in BTC were millionaires last year. This year might be a bad one, but there is always a tomorrow.
