when we decide to invest it means, we are ready for any consequences that might happen later and if something bad happens, we don't have to regrets and we need to search another way so we can still make a profit. so before we invest, we need to know everything about the program investments so we can know that every investment has the risk. besides that, don't put all of your money in one investment only, it is better to spread in many investments and if you decide to invest in cryptocurrency, you need to diversify in many coins so you can have a chance to make a profit from the investment.
Bitcoin is one of the digital currencies that will become the money of the future, to get to that stage bitcoin will experience a period of glory and a grim period, prices rise and prices fall. Such a cycle is certain. So invest your money in bitcoin, I'm sure it will rise again. Next year my prediction of bitcoin prices is around US $ 15,000. For other coins, I don't think it will be as big as bitcoin.
