Most of the time we regret buying something when we see the price drop. Then we don't have any more dollars to buy. But if we divide our total dollars into three or four parts and buy slowly at each down, then the chances of profit are high. And if we get profit after buying first, then we will sell. For this reason, I think it is better to invest little by little instead of investing all the dollars at once. What is your opinion?
It seems like you don’t know the theory of trading strategy, because this is what averaging is. You will never invest all your capital in a single trade, you should invest one-quarter of your money to reduce your risk of losing all. This wouldn’t have been hard for you if you engaged in research and lessons or tutorials about trading and even investment. But most of the time, newbies think it’s just about seeing a coin dumping, then putting your money in it, and if it pumps, you get your money back, which is not always the case. You have to know the strategy, understand the risk, and make your analysis, because there are some altcoins that, if they dump, will never rise again, and that will be a loss for you.
So, if you really want to get a good profit in trading, then you need research and learning.
