Believing in bitcoin will be necessary if people want to invest in bitcoin and not panic if the price is down like today because bitcoin is not weak as they thought and when the right time comes, bitcoin price will increase and will break the high price.
Anyone investing in Bitcoin should believe in the market and even if the price goes down there is no point in panicking because you should be confident that the market would reach those valuation at a later period of time and if you have the bank balance you should average your investment capital if the market goes down.
Since i have seen the market going down multiple times and in the past i was confident about the price recovering but this time around i am not too confident to invest during a correction until the market settles down as the price is really high. Expect more FUD news to come out in the coming days that might pull the market down.
