What do you think is/are the reasons why the two of the world's most richest men doesn't support and is against Bitcoin and Cryptocurrency?
I guess the most probable reason why worlds two most richest and I think the wisest man are not in favour of bitcoin is may be because of decentralising nature of bitcoin and because of which bitcoin is now being use for illegal activities like selling drugs, explosives, money laundering etc and the advantage of bitcoin that provides confidentiality in the transactions to its users are encouraging such illegal use of bitcoin because bitcoin transactions does not involve any third party seizure and I guess this could be reason why these two are in against of bitcoin.
