I will never sell all of my coins in one time becuase i know that people are getting mad by putting everything for sale you can better keep some of your coins ytou will never
know what the price will do.
That is true. If you think the bitcoin price will rise in the long term like it did in the past, it is better to hold.
I think the most users of Bitcoin believe that the Bitcoin's price will increase highly in long term; but not all of them are holding because as Bitcoin is money we need to spend it sometimes.
