So are you think time now is
too late or some one in future will say how price was cheap in 2017 like my post
Shear what you think

When I got into Bitcoin around 2014/2015, I usually see some people discuss how Bitcoin was cheap in 2009/2010 compared to the current price as of then which was around $200 and $250 (price around 2009/2010 seems to be $0.07/$1) so you can see that the price of Bitcoin was very cheap in 2009/2010. Now this is 2018, I will advise you to buy at the rate youre seeing.
You did a very accurate comparison. If we have money then we should invest now. Do not look at the past anymore, we have a real lesson.
