At first when i convert my peso to btc during high price value of bitcoin, the charge fee is high, and that time my mind thinks it's not fair. But later on i conclude that the charge is reasonable. In other words, the higher price value is equivalent of the higher total returns to everyone who invested in it. But at the end of the day, we will be the one to make decision whether to invest even if the charge is bigger or we're going to drop before investing.
