I like trade for
btc-usdt for maximal profit, all exchanges have decent volume of that pair so just choose wisely, choose the exchange with minimal trading fees like kucoin and binance!
Your choice is very right and not wrong, but if in the past two days you have bought Dogecoin tokens, then today you already have the maximum extraordinary profit even you can get rich suddenly because Doge's price movements are fantastic even beyond everyone's predictions.
