Actually a ninja launch is wat seemed most fair to us. With Grin, everybody and their grandmother knew the launch was coming. The network was dominated by big farms from the start making it almost impossible for small miners to find a block.
With Grimble, everyone can mine right from the start. Even though there isn't a public pool yet, you can use your own wallet as a "pool"
(it has a stratum server included) You can even rent hashpower if you would like.
If you do not understand this, I agree, it is best to stay away. Others will take your place

Happy mining, we're here and on Discord to help out!
