I’m currently creating courses for beginners about DeFi and NFT, but should it Vidéos or Articles ?

I’m working on an education platform to help beginners learn about DeFi and NFT. (The courses will be totally free for students)

The goal is to help people participate in Web3 on Lending/Borrowing, Decentralized Exchanges, Buy/Sell NFTs, Gaming, etc…

The courses will give certificates in the form of NFT.

But, I don’t know if courses are better in the form Videos or Articles. Both will be visual and should be understandable by a 10 year old but I feel that Articles are scannable and read through quickly while Videos require less mental effort. What do you guys think? Videos or Articles ?
