Just found a group update of 500 Bitmain Antminer S19J Pro+ 120T for $1919/machine; brand new with warranty. I checked energy costs for my area at about 8 cents /kWH.

Seriously thinking of buying one or two for myself or trying to convince my school of buying some and letting me teach students how to use them. I would first have to learn how to mine, but what a learning experience for myself.

Me👇🏽 currently…
