that very depends on your ambitions and plans for crypto. I prefer trading, coz I like the process. besides, DEFI is trendy opportunity now - you can check it. A lot of exchanges already start some platforms and list these tokens
heard that cex.io announced defi platform and enable credit card purchase of tokens and they have zero fee campaign till september
Hope they extend it till next month, October. We're about to end September now so you should hurry up especially from what I know that CEX.io requires KYC?
My answer to OP's post is that have both ways. You need to trade whenever you see it benefits you for buying or selling the digital asset. Also you may need to hold on to a few digital assets too as you may never know when those assets will go boom.
