No, never.
If you look at the market, any market really, you can find numerous reasons to spend your life regretting. There are so many missed opportunities that you can regret day in day out.
Rather than doing that, train yourself to focus on the next trade only. That way you will never engage yourself into things you cannot change.
It's never too late to educate yourself the proper ways, change your mindset, and start trading. Focus on the positive, avoid the negative.
there is no word late in the trade, because the delay can make us able to take lessons from the ups and downs of prices that have happened, so there are always opportunities in bitcoin trading, the more we understand the potential of coins, the more opportunities we can trade to find profit, hopefully we can always make the right decision.
