A friend asked me, #Neiro and #NEIRO , do you bet on it? Which one do you choose?

I was a little confused after hearing it. Why are there uppercase and lowercase letters, one for spot and one for contract?

After thinking about it, I think, they are all memes, and they are all the same.

Either buy none of them, or buy half and half, anyway, it's all a gamble.

What do you think?
