Bitcoin already have great achievement in past 9 years. From dont have a value and bitcoin price right now at $6500, highest price at $19k. I am believe bitcoin is good long term investment and still valueable investment
Bitcoin losing value because of greedy people who are trying to manipulate this market. Of course every market needs to dump so people can buy at a cheaper price and sold when it reaches the moon again. Bitcoin and other cryptocurrency are both great in the future, so better to keep on holding and become rich in the future.
