The final cost come out to be just a tad over $1,000 so its pretty expensive which would be about the cost of 10 raspberry pi so cost wise its not far off and power wise it comes out to be about the same. I should be able to run about 15-25 POS wallets on this machine at the same time. Granted my ISP does not kill me for the bandwidth lol
15-20 POS wallets, that's a lot. If you don't mind me asking, how many different coins are you staking?
