Hello guys it's been like 3/4 months I have been playing Alien Worlds I want to invest something like under 10$ if possible max 20$. 

Some weeks ago I was getting like 1/2TLM per mining session and at the moment getting under 1TLM with same tools and same island this is the reason that I want to invest in the game. If possible tell me best tools under 20$ to buy and best places to mine.

At the moment I'm at 18:7 for cryptomonkeys at Neri. Thank you everyone.
