So why am I buying now?
Exclusivity
Firstly, there will never be more than 21 million bitcoins. There are more millionaires than that. I like to own something that not every millionaire will be able to own. Its exclusivity. I own something that has a limited supply, so not everyone can own one, but Ive got lots of them.
Yes it is more important thing,the quantity of bitcoin is very much limited when comparing to the world population so if you can have some bitcoins and in few more years the real value of bitcoin will evolve at that time the early investors will get more benefits.Even now the price of bitcoin is very expensive when it was used by very small community of people and let's imagine the value when whole world using it,you will become a millionaire even if you hold few bitcoins.
