If you really believe that the coins that you have are of great potential, then , I suggest, secure and hodl it until it reaches your expected or desired profit from it. But if you aren't that confident in them in long position, then you can just trade it. Hodling and trading are two different entities, and each strategy depends on the potential of the coin, your target for profit and your motivation and circumstance. People who have made crypto their bread and butter and need to generate returns quickly go for day trading, regardless of the fact that the coin is a safe bet. But if you have a decent amount of capital that you can afford to invest passively in cryptoassets that have long-term potential and still undervalued, then hodling is a good strategy. You will know which coin is a good buy by looking at its market cap, the team behind the project and the echo or the buzz it creates in the cryptoworld.
