Ignore the letter. Pay the bill. Send all your coins to cold storage every day, so if you do get raided your coins are safe. If mining in a pool, there should be an auto-withdraw address. It's been 2 years since I was mining any proof-of-work coins, not counting experimenting with new ones that appear.
are you being serious about this. the more thought I put into things the more I come to the conclusion it would be silly for them to raid over electricity once they confirm no massive grow op.
I have always LOL'ed at the grow op anyway. Simply because you would have to stack an entire house with a muli-story (meaning two levels of grow per 8ft ceiling) to have the same power density as a btc farm LOL.
btw its next to impossible to have two 4ft grows stacks on top of each other and highly impractical.
That being said nobody looking at the raw data at power station probably runs the numbers to that level, or maybe they do. Regardless if you did you could clearly see its impossible for it to be a grow LOL.
Looks like I'm going to have to pay a $5/kw flat rate plus a $30/month charge every month. Not bad. Starts jan 1st. May be a little off on pricing because of bad memory but think that's right.
