You are never too late, because the market will increase from now on for many times. This is the best month in the history of BTC because I think it has never made such a big step forward during one month. Fasten your seatbelts guys, the red days are over, we are going to the moon.
In business it is never too late, because prices will always increase. Start bitcoin investment from now, when the price is still US $ 8000, because in the future the price can be even more expensive.
The fear of falling prices certainly haunts investors who realize prices are already high, but it must be remembered that bitcoin is very volatile and prices have reached US $ 20,000 in December 2017. So it is not impossible in the future that prices will reach that level again or even higher.
