but people are too scared to buy bitcoins as they donot have the knowledge of technology.
this is always thing.
So the best id but bitcoin as long as you can it will make you profit for sure.
People's ignorance is kinda lame excuse, it is not hard to sit for a couple hours and read basic information about Bitcoin.
If you can use simple math it is clear that Bitcoin's triumph and continuous price growth is not gonna suddenly stop right here and now.
There is still plenty of room - we have only 21kk Bitcoins and more than 6kkk people on Earth - just do the math.
