Why should I not believe in Bitcoin because the most important thing in Bitcoin is that you need the patience for it otherwise it will be not possible to make any profit.
The most people are greedy and that is bad because they dont have also the patience for it.
If you want to make good money form it and you have to wait long for sure, and if you don't have patience then you are playing with your investments and profits.
Why do you need to wait for bitcoin to become worth thousands of dollars?
You can still enter quite a good money if you involve in altcoins and still you have plenty of time for bitcoin to catch train.
