Bitcoin can be dumped by 30% for various reasons, one of which may be bad news in the market. Moreover, I think that the Bitcoin market is not always in a high position and will not be, there will definitely be dumping. If the Bitcoin market is not dumped, but only in a high position, then it will definitely not be positive for traders and investors. The reason why Bitcoin is so popular today is because of dumping and pumping in the Bitcoin market, so 30% dumping is normal, there is nothing to worry about here, now the market has been dumped, maybe it will pump again.
Yes, it is true that the price of Bitcoin can be downward for various reasons, which is 5% dumping. Many times the price may be reduced for bad news in the market and selling Bitcoin to big holders. We saw Bitcoin prices drop sharply when we were hacked because at that time many investors had sold Bitcoin. According to the comments you mentioned, the price of Bitcoin will not always be in the same position, this example is that Bitcoin had a maximum of $ 5K at a time but it was dumping $ 5.
Suddenly 30% dumping does not seem normal to me, but this time we have to be very patient.
