I think the idea of bitcoin being the to put investments is because of its fast pacing. The value of bitcoin really change so fast so it would be a huge earning when you already have a large investment because at that time you can sell your bitcoin and earn triple more than you expect thats why it is really the best to invest in bitcoin.

I think that is because in the long run, people tends to be used in the fast changing price of Bitcoin and that is not dumping but they are used to pumping. Since the price are changing fast, they always think that it will always be a pump and they are scared of the dump. They are complaining since they are scared of what may happen in their investment.
