i am new to the whole nft environment so please enlighten me!

1. how these cards will gain value? (From our communities? will have a fixed price?)
2. Will artists get paid and how? (i am no artist just curious, they will gain a percentage or something etc etc)
3. how am i eligible for the giveaways? (should i create a wallet somewhere like in this wax blockchain?, is it sufficient if i am active on discord?)
4. are there any other links to learn more?

sorry for the too many questions :P
