if i trade altcoin with USDT as it's stable and equivalent to usd ,so i can get my calculations .on the other hand trading with btc isn't that much profitable or sometimes not profitable at all if btc price gone down
I think worst to exchange the altcoins for USDT. It same like you are converting cryptos in fiat cash. If you are looking to make the profit. I suggest you to invest your bitcoin as much you can even if you have fiat cash put on that.
With in 3 months you can expect the double the profit for sure mate.
Holding is the strategy you need to follow to make the better profit soon nothing else works.
