there are many people that did not buy bitcoin because it is expensive and at the end of the day they will end up with a very big regret, even in year 2010 people did not buy bitcoin that time because they think bitcoin will become failed and even 0.5$ price is look so expensive for bitcoin that time.
if you were, did you buy bitcoin in 2010? i see your account was created in 2011, it means you know bitcoin very early, so did you buy bitcoin at that time?
i dare to bet you that you did not dare to buy bitcoin at that time, no one could have predicted that bitcoin could achieve the crazy growth rate it is today, no one thought that bitcoin could come from a bogus, valueless virtual currency that could increase in price by tens of thousands of dollars
nothing to blame here, we would never risk buying something we know nothing about, that's a very normal thing, but we'll regret seeing it grow
but it's never too late to invest in bitcoin, we can start investing now because bitcoin is very potential, it can grow many times in the future
