These are reality in bitcoin life because here the fact of 64% , may or may not be wrong but one of mine friend is in bitcoin since 2010 at that time the value of bitcoin was totally very useless like and a site named like mtgox was where he has lots of bitcoin ( about 20000 btc ) , as we know that value of btc was very low but due to some government issued and hackers the site get hacked and that site after that never come back in his memory , so here we can understand well that at that time may be many people who putted thier btc get lost .
Well these strange facts are really better but the next interesting fact that I think is that complete mining of new bitcoin will not get stop , Because after mine of single bitcoin results into toughness of mine another next bitcoin .
