One way or another, if someone invests in Bitcoin for the short term, so that if the price rises immediately to get real profit, then he will still have to wait a certain time to be able to make a profit, and none of the ordinary cryptocurrency users risks big capital for investments in cryptocurrency in order to quickly get a good result, because the market is unpredictable. That is why everyone expects when Bitcoin will rise in price by at least a third. If today we have $ 7,000, then the best investment is for a period until Bitcoin rises to $ 10,000.
