Anytime is a good time for trading provided you know in which coins to invest and when to buy and when to sell. If you are clear about this then you can trade at any time.
Yes indeed, when we are having good trading strategies then we never worry about better time for trading. Automatically we can have good time with our trading by choosing the right coins for buying or for booking profits with the coins which we might have bought previously.
Better time for trading will come automatically to favour us just to make profits only when we are having strong knowledge on technical analysis.
