No, I do not think that it is too late to buy bitcoin. Bitcoin is still an evolving currency and there will be many price increases for the future years to come. More and more people will be looking at getting into using bitcoin and this will drastically bump up the price, even though it has already increased drastically in the past few months.
You are in right direction. I think it too much early to take benefit from bitcoin. Bitcoin has been introduced yet in 2009 and it is 2017 so how can we say that in 8 years of life bitcoin is near to die. It is the 1st cryptocurrency of the world and now understand and getting interest in it. Mostly people are unaware of bitcoin when it became in his use across world then the price of bitcoin will go very high and I think it will be 2050.
