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.
If you choose to invest in altcoin it is hard to know if what altcoin is the best to hold that we can make a fast and large profit..
Almost newly release altcoin is the one who are increasing fast unlike legit and long live altcoin that you can hold it for a long time just like bitcoin that you can be still make a profit so dont always stay at one altcoin choose the top 10 altcoin in coinmarketcap..
