Maybe people think that there's change of mind towards bitcoin since somehow they see those famous personalities who hate or say something bad about bitcoin before which turn to be a bitcoin investor now.
But I really think its so hard to convince the old man to invest with bitcoin since for sure that he's already fine with many ventures and he's still think that bitcoin is gambling token base on his past statement. Maybe best for people to forget about those guys which have negative thoughts on bitcoin and maybe they should focus on those people show their interest to put some money on this coin and believe that this is good asset to invest.
With how old it its, why he just won't relax and put the show and awe from BTC away?
I mean, if a person is that rich, he can say whatever he wants, and it won't stick too much for the communities just because it's obvious that BTC is great in so many things that for him would be seen as bad or a Ponzi scheme..
