Guys help me out here to understand.
So I bought BTC at 6200 and its now almost 6700. Now should I sell it and go to USTD, or go for something like XRP/BTC or ZRX/BTC?
Depends on what you want. If you go to usdt, then you will earn the difference between buying and selling. If you go to altcoin, then pay attention to the cost of altcoin at the time of buying bitcoin at 6200 (maybe at that time ZRX cost 0.000134 and now 0.000167). This way you will get fewer coins than a few days ago.
