That's weird. You should be able to earn from your Youtube channel already as a content creator unless you're not actively uploading or not getting enough viewership from it. If you're having fair amount of subs, likes and views, you should definitely apply for Youtube Partner to be able to monetize your videos and you know the rest already.
For sites, not sure if you built the site from scratch but you can start freelancing business either as a backend, frontend, or full stack dev. Not sure what country you reside from, but clients usually pay a lot in freelancing. There are freaking lowballers, but a good and well-paying client should be there.
Yes to be partnered with youtube is really hard you need at least 4 thousand watch hour and Im still at a thousand currently and need 1000 subscriber and i have 1,4K subs now but to get 4000 watch hours is tricky part since I only have short video but when I uploaded long video no want watch it
Why I dont give up because monthly view is already reached 1-2K so I dont want to give up now hahahha
For the site Im making Blog and basically dont have really specific niche so I throw it what happened in my mind
and for the OP i just quick search that Grab Holding that listed on Nasdaq according to
