RE: Head Scratchers & Hype Trains

Right now what's got me excited the most is Splinterlands. It's a learning curve for me but I'm working at it. I love that it offers me several ways to earn as well as several tokens to build upon.

I also want to know more about NFT's and how to obtain them?
My budget is an the low side so where can I find the less expensive ones?

And also I heard that the cards in Splinterlands are also NFT's, so how do you obtain the NFT of those cards?
