The point is that if you could make $100k from $1.5k in power then it makes no sense to not do it in a data center where you don't have to move the computers around and break them.
if your projection was for making $1,000, but then because spiked up to over $4,500 an ETH, that it's suddenly lucrative, it makes sense. cryptocurrency's been on a wild ride so a projection that they'd only make $1,000, but ended up with $100,000, isn't impossible.
If they'd make $1,000 I'd believe it.
