Holding bitcoin for a long time is a good strategy in earning because we always says that someday bitcoin value will rise veey high so that if that happens we will sell our bitcoin and earn a good profit. But I always think that how they will have income if their only holding their business bitcoins. I suggest to those who will hold their bitcoin in long term that they need to have a alternative source of income in able to have earnings even if they are waiting and holding their btc.
