many of us have regret today because they are too late to buy bitcoin yesterday and now they see the bitcoin price increases higher. besides that, if we can buy bitcoin in the yesterday, today we can sell it for making a profit or we can hold and waiting for another increases the price. but you don't have to regret for a longer time, you still could buy bitcoin for now if you want but be careful to do this because we don't know if it's just temporary or it increases higher.
