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.
It is never too late if you wanted to buy bitcoins because look at the other people that just started last year they also asked the same thing just like you but still the have manage to obercome their fears of maybe they will just lose their money at all. The great yhing in bitcoins is volatility and be thabkful to that because if bitcoins is not volatile we all late comers cannot join anymore but they are now in a lower price we mist take advantage to that and do no hesitate to join
