In order to find the one trading strategy that will bring the maximum profit, it is necessary to test many trading strategies. And even when you have found the only trading strategy that you think suits you, you should not focus on it, but continue to test new strategies.
To find a suitable and effective strategy, you need to spend time analyzing the market and at the same time you need a large amount of capital. I think the appropriate strategy in trading is to buy reliable coins and accumulation regardless of the price. As a result, the holdings in the portfolio will increase and the unit price will continue to decrease. This can be a decent and reliable strategy. Buying at lump sum creates a risk on your capital, so buying gradually is a better trading strategy. This is to try to increase the buy level as you understand the market situation.
If anyone has a suitable strategy, it is possible to make a lot of profit by trading. A person should always observe the market and select coin and trade it on that coin. But according to your comment, it is Buy the dip. But it is not suitable for trading, it is good for investment. Because an investor adopts this method, when the price of that coin falls. Anyway it's a very good technique. But yes, an investor should not invest in a coin, it can lose huge amounts of money if the market is in a bad situation. On the other hand, a trader can always benefit, if he can observe a good amount of prophecy and market. And if a strategy is effective, then that strategy must be firm.
