I started playing Axie Infinity about 1.5 weeks ago. It's an interesting concept to say the least and I think it has potential to change how we look at a gaming economy. The initial investment is pretty high...i spent .6 ETH which was about 1500$ at the time to get started. This gets you 3 playable Axies( 3 NFTs on the blockchain) to form a team. The Axies you buy have skills in the form of cards that you use for PVE and PVP. In game there's a daily quest which consist of winning 10 PVE rounds and 5 PVP rounds. For completing this daily quest you get 50 Small Love Potions tokens, which at the time of this post 1 SLP = $0.1778 so about 9$. On top of the daily quest you get some SLP for winning in each round in PVE and PVP if you have Energy left (how much you can earn while playing in a day), which starts at 20 Energy. I heard the max SLP you can get in a day is about 150-200, but not sure about that.
In this 1.5 weeks I have 1128 SLP tokens (200$), which I can sell or start to use to breed my Axie's. I haven't started doing this because my Axie's aren't great for breeding, but once I get my initial investment back, I might try to start doing this because you can get a pretty large farm going and the cheapest Axies currently to buy are about 350-400$, but it cost about 200$ to breed.
There's even another way to make money in this by doing an Axie Scholarship, where you basically buy another team of 3 Axies and lend those NFTs out for someone to play for you. You claim their SLP on their behalf because it's in your account and split the profit with the person who is playing your account. Apparently this is why it's huge in the Philippines, because it's more profitable to play this game then getting a real job. It's pretty wild and kind of scary at the same time. You should see the Discord for people begging to have a Axie Scholarship, it's non stop! I guess you can get banned if it you don't do it correctly so I haven't bothered with this yet either.
There's still a ton I am trying to learn about this, but if I get my initial profit back I'll enjoy the free money I get for playing this every once in awhile. We'll see if I do though. I just wish the game was little more exciting. It's not god awful, but it's also not my favorite card game.
