The first investment I ever made in a play to earn other than my Starter packs for Steemmonsters was a shovel. I had no idea what to do with it but it turned out to be an easy game. It was just a clicker and it was popular.
I started playing about 6 weeks too late and their trillium token earned for mining had reached $7. Its now worth $.02 and while still popular it seems meaningless to click your "mine" to earn so little.
When the game started you could find NFTs on the land you mined and I got lucky with a Quark Separator and a Draxos Axe which to date are my highest valued NFTs that someone would actually buy.
I was told at the time that I was lucky to have gotten the Quark because there were so few given out but I was hoping to get more and more and more. But I didn't.
The game changed to combat bot mining and for many many months nothing was happening there. Just click for shit. But I clicked.
Then a few months back they changed how you could earn NFTS. You simply mine and accumulate NFT points. You can save them up and buy any NFT offered as a prize on the NFT exchange within the site.
I didnt quite get it at first because the prices were how and the points you earned were low but they began to accumulate. I was able to save up 4,000 points in about 3 weeks and bought a standard drill.
I already had one but I noticed that was the lowest priced nft I could get that would sell on atomic and it was selling for $4. So I got it, sold it and bought a chaos legion pack off of atomic.
I've done that twice so far and 1/3 of the way to my next one. I figure clicking a button while i'm online and getting some wax and chaos packs is worth it. It seems to be about $6 a month of earnings for me.
Maybe it's time for you to revisit Alien Worlds if you had an account and lost interest. You might be able to mine in a way that is worth it for you.
