choosing to trade and then using a holding strategy is a combination that works well. both strategies will provide benefits.
trade to take some profits on market fluctuations with the scalping method, but it would be better if you use a large amount of capital. For holding buy some altcoins at the bottom price and then hold them until the price reaches bullish or hype. For example, holding altcoins such as shiba, doge and altcoins that have potential in the future.
I like your plan, combining these two strategies can be more profitable. However, I think it is more suitable for those with long experience. For those who are new to the crypto market, they will have some difficulty in daily trading because they do not have too much knowledge of analytical methods, they need a long time to research about crypto and related issues
