That is a big change after 1 year. Trump is known as being against the cryptocurrencies but the interest in Bitcoin of the people of the U.S.A is increasing very quickly. If it goes continually like this, the government may not think of banning cryptos not ever.
No matter how tight the government is in implementing rules against cryptocurrency, it's still up on the people's discretion and prerogative to choose what to do. People are already enlightened and exposed to crypto making them want to do it and have it more. They already knew what are the advantages and the good side of cryptocurrency, how profitable bitcoin could be once started. Also, people are already suffocated with the government's interference with their lives that's why some cryptocurrency's decentralization like bitcoin is such a relief.
