I do not even have the courage to buy Bitcoin. Although I believe Bitcoin a lot. Many of my friends have made a lot of money by investing in Bitcoin. So I am thinking that I will buy Bitcoin in the future. As Bitcoin too Rising to 5000+ USD
WHAT DO YOU THINK ? 
I think you should still go ahead and buy small quantities. People made the same mistake over the years. They wait for a dip to buy Bitcoins and they keep waiting for ever. In the long run, it might not matter whether you purchased at $5000 or $6000.
