This not true as 2000 NGN i just $3.4 with the selling rate at Binance #584 and believe many exchangers has set limitation of trading, mostly Binance is $10+ so i don't know how one can trade with 3.4 and become that rich or successful. I can easily be convinced by buying and hold maybe you started with just NGN 2000 as the case maybe, you kept on topping the BTC in your wallet before the price break out. yeah this is a genuine reason.
