Anyone who invests in bitcoin, when the price of bitcoin is above $ 15,000, it is very risky in my opinion and indeed it can be said to be foolish, because by buying bitcoin at that price, it would be difficult to get big profits, or even cause losses. I think being patient is waiting for the drop in bitcoin prices, and start investing when the price of bitcoin is in the range of under $ 7,000, by investing bitcoin at that price, I am sure we will have a great opportunity to be able to make a profit, and will reduce the risk of loss.
