The presidency of trump is the inclusion of bitcoin supporters like Peter Thiel and Mick Mulvaney in his team.. also trump is considering the bitcoin entrepreneur Mr. Balaji Srinivasan to head FDA. Balaji is the founder of one of the leading bitcoin startups. So and there are more bitcoin enthusiasts are there under trump's governance. So we can believe that the trump administration can be more acceptable of cryptocurrencies. So Traders need not worry!
It's not just the people whom he took in his team, some of his campaign slogans say that bitcoin will not be ignored, for example if the financial wall will be built with Mexico, the people on the earnings will go to bitcoin to send money home.
You are seriously overestimating the technical ability of the majority of the mexican migrant workers.
They walk around with wads of Cash, because they don't trust Banks or credit cards.
Most they do is money orders with the US postal service, or another money transmitter.
They have to have a bank account to buy BTC , and if they use localbitcoins instead, odds are they will get robbed since they always carry all of their cash with them.
So far their has been no mention of taxing their remittance back to Mexico only imported goods, so it would have no effect on money they send back with money orders.
FYI:
Plus after the wall is built the illegals won't be able to get here to send money back to Mexico,
the ones that are here legally usually move the rest of their families here year round and don't send money back.
Only the illegal ones that work thru the growing season for a few months and then return home send money back like crazy.
