How can this be a stupid idea ? It is not. In fact it is the best way to have profit. If you buy low you need to wait for sometime for the profit to accumulate before you sell and that is buying and selling later, so is there anything wrong with that ? No there is not but the way that we can hodl for more profit. No body invest with out the aim of making profit and making profit is gradually and hodling coins is just about that. We need to hodl longer for profit.
