The same things everyone else does with their Bitcoin, you know, trade it for USD.
(I'm just kidding guys, please don't lose your shit)
I think it is quite difficult to trade the bitcoin with US dollar and get a lot of profit. It is better to hold the coins.
Its not worth to trade btc to usd, better choice is to trade btc to altcoins where the chances of making profits are higher and if you have good capital then results would be even better.
