What’s the cheapest energy solution for American miners due to 120v standards here?

1) Buy a step up/step down transformer to convert to 240v and buy a mainstream miner

2) Buy a cheaper miner that’s lower hashrate but runs on 120v just plugging into the wall

Adjusting the breakers/wiring is not going to happen and I’ve heard using the dryer plug is not safe.

Any insight from fellow American miners? #Mining #BitcoinMining
