About Donald Trump, it's either he is the one that will take over with his own port folio to bitcoin. We all know him as a businessman it's another title for him. And we know that businessmen are into making profit, as long as he has enough background to it and he has the capacity to put his entire wealth into seeing the possibility of profit.
Do you have any reference about i have read the US government planned to acquire blockchain technology and two months before they had meet and US commerce department went to blockchain and discussions were around 2 hours. Check in google for further reference about it.
I just read it somewhere here on forum. Maybe you can try to read this news
http://www.coindesk.com/bitcoin-blockchain-trump-go/I'm thinking that Trump is truly doing something already with the possible research with blockchain / bitcoin to be specific.
Fair enough, so we can consider that Trump has a role in ETF decision :
Attendees of the event included the acting chairman of the CFTC, J Christopher Giancarlo (via teleconference), who has embraced Trumps 'Make America Great Again' slogan as part of his own agency agenda. Also there were a number of lawyers from the SEC, the National Futures Association and representatives from large law firms and investment banks.I think some big names will invest on bitcoin if SEC approve winklevoss ETF as a regulation is needed to put their big funds.
Or maybe some of them already invest on bitcoin but keep it on silence, nothing for sure without any legitimacy.
