For me i think buying bitcoin its not too late because the potential is still increasing and it will definitely maintain its top spot in the crypto currency world. Unless there would be rumors that will affect bitcoin. But being the mother of crypto currency it would be harder to bring bitcoin down after all this years bitcoin continue to rise.
to me i think it is never late t buy bitcoin and get profit from it, in fact bitcoin will continue providing benefit to me at any state. i think the present price is the best price to trade bitcoin, because currently bitcoin is really trading in a low price and therefore i think that we can get a chance to make moneybox from bitcoin investment.
