let look at it from this angle. Imagine if Tyler and Cameron Winklevoss who bought BTC when it was $7 had sold all when the rate is at $50. What do you think it would have happen to them now that BTC is over $50,000?

i am sure they will be regretting very well. the truth is that we should invest more than thinking of selling more because no one knows what could be the out come any investment
