For me Hold has made more money than trading. If you want to invest and learn use the testnet, that's what they are there for. Not your precious crypto.
But that means you will be dependent on one cryptocurrency.
The most popular cryptocurremcy in the market might be Bitcoin but it is not the only cryptocurrency you could depend on. Holding is great but I think you should also try to diversufy your cryptocurrencies while you can to minimize the risk you are taking. Try to invest in other cryptocurrencies as well, then trade to another, if you can't trade well, then just hold them for some time.
You have every options, just try to work with what you think you fully understand.
Crypto industry provides a lots of options if you want to succeed you better to find ways to advance yourself.
Trading or holding are both profitable only if you know how things works and how you take your advantages.
