I think it depends on you. If you have a good sense of market then you can trade. It can be more beneficial in a short period of time through trade. But there is more risk.
But in my opinion, HODL is the best at the moment. Because it is less risk. If you wait patiently 100% benefit.
I think ,You can do both for your profit. if you want a long-term profit you keep your Altcoins , Although they have a possibility for profit.
Remember that there is always risk in trading . If you can control your emotions and trade, then you can eliminate the damage and will be success
I do both to earn profit. No one is forbidding us to do both trading and holding at the same time so why bother if you can do both. Trading is good if you know how you will do the trading while holding is good for long term investments. I also participate in campaigns so I can earn bitcoin or token and the token that I get is what I used for trading. This two makes a good partner if you want to save for the future. Not all people are able to do investing especially with the high price of bitcoin so some would prefer investing in altcoins. This is also a good idea but of course, one must be careful of what token he is going to invest into because not all altcoins are proven to be profitable.
