I thought about Stone Miner, same as Bronze Miner. Ended up with some Cattle Ranchers due to the sale.
Sure I won't get heaps and heaps compared to others that will buy up many more, but I can at least get some decent token mining going when that is implemented!

I think the Stone Miner is either a whole lot of small buys from people with less amounts or a few people buying bulk amounts while it is the cheapest one and easier to buy up a lot of.

Got to get in while you can though and prepare for the mining to build a supply for when governance comes knocking.
