Bored, want to do something online

Good day lads.
Im currently not very productive online. I do have a normal job but im looking to do something during free time. I used to sell tiktok accounts, that didnt work for long. Now im stuck with one tiktok account with decent following (idk if its botted or not but the acc is russian...). I have around 7 devices that I can use. Not sure what to do, what to post, promote and so on... Open to your suggestions.

Do what you are good at create multiple accounts and sell them. You already got 7 devices. It can be anything don't have to be tiktok.
