I like as there showing their interest in something and you are helping them with their dream.
I also follow them on youtube and will be the same when they get on twich too.
I will like them to try out the Biggest NFT blockchain gaming That's SPLINTERLANDS. Once they start understanding this game they will love to play and also earn reward cards that could be easily turned into thousands of dollars later in the future of Splinterlands
Here This is my link to the Splinterlands if used I will send them some DEC to start with.
Good luck to the little ones
