Say 1 BTC was worth $10,000 for simplicity. 65% increase would mean $16,500.
Now your MANABTC trade doubles so you get $33,000 total (2 BTC at the new price).
That's why we trade Altcoins vs Bitcoin mainly long-term.
With USDT if you buy $10,000 worth of any Altcoin and it doubles you get $20,000. That's it.
