Well if we speak about gaining on bitcoin i think there is no required time on making an act of productivity.We can really buy bitcoin anytime anywhere without any hesitation and we really didnt have to be afraid about the price because dropping and pumping is really the nature of it and we really need to make sense of it so that we can become more productive and we don't feel like panic all times.
True, if we want to get bitcoin requires patience and strong determination. Bitcoin is just a digital currency whose numbers are limited. So for that it can not die prematurely. We do not have to worry about bitcoin by walking alone the opportunity for us to be able to hold more bitcoin.

No I do not think that it is too late to buy bitcoin.In my opinion there is no such time limit.You can buy whenever you want to buy.We do not know when will the price rise or fall.But yes now a days the price is low and is rising slowly so one can go for it.People hold their bitcoins for future price rise too.I think bitcoin is an opportunity to make a lot of money and that too in a short period of time.Bitcoin is like an extra income.People who have bitcoins can live independently.
