It is not late to buy bitcoin, in the near future it will get doubled.
I agree with you, It's not too late to buy bitcoin, as you said in the future it will be the double, and maybe more, no one can predict how price of bitcoin will be in the future, but all of us know that bitcoin price increase every period of time, so it's a very good investement.
So, I advice people to buy bitcoin now, before it will be more expensive in the future.
The problem is that I have been telling this to my friends a long time to go, they thought that paying 600 dollars for each bitcoin was simply too high and now that bitcoin is above 4300 they think the same, they do not understand, they only see the price as it is and not the potential that bitcoin has to grow to even greater heights at the end they are going to regret it and I will have no other option but to tell them I told you so.
