but if you want to gain profit quickly, you should be a factor of TA and FA
Best time to invest is when the price is low. Trading in low price can gain more profit in the future. But the real thing depends on you. And make sure that you also choose the right coin for you.
How do you know when the price is low? That's a really stupid thing to say, most people say it but they obviously don't trade. Is 7k low? Is 10k low? How do you determine the low? What if it never recovers and 7k turns out to be the high?
indeed to determine the low price it can not just by saying it, can at any time the price will continue to decline after buying it that we assume has reached a low price. at least if you want to buy it when the market situation is trending up after experiencing a fairly deep decline, so can say the price is low only when there is a considerable decline in the price point
