"Then those games don't get crypto even less than gamers or Ubisoft does." - Ah yes, because Ubisoft gets it for everybody else. We are just sheep that need follow what they say, thinking is overrated.Then those games don't get crypto even less than gamers or Ubisoft does.
Ethereum had God and everyone pack onto the protocol for DeFi, games, NFTs and now the network is so congested you have parasitical protocols like Loopring and Solana cropping up just to sidestep Ethereum or be layer 2 solutions and become top 10 market cap in the process. You're very badly informed on the state of crypto if you think Eth or BTC are the 'only' cryptos.
I never said that BTC and ETH are the only cryptos, they're just the only ones that matter. Do you have any idea just how many alt-coins came in trying to "fix" the problems of these two and failed? Show me the numbers, the trade volume, the market cap. I can easily do that.
EDIT: Try making an account on OpenSea. What is the first thing it asks of you to do?
