The S9 will probably add $1000 a year minimum to your electrical bill.
Sounds like it would eat the same amount of juice as our swimming pool does.

Just to note that's for Bitcoin only, which is the most energy intensive.
Yeah so to expand on this Bitcoin uses the SHA-256 algorithm for mining. If you read back during the Bcash(Bitcoin Cash) stuff it also uses SHA-256. So mining pools early on were alternating between the most profitable coin. Bcash built in basically an emergency switch if x number of blocks weren’t mined in x amount of time it would recalculate to be easier to mine. Bitcoin automatically recalculates the hash rate difficulty every 2016 blocks, which is about 2 weeks worth of work(goal keeping block creation ~10 min per).
For Bcash mining pools took advantage of this by not mining blocks in the set time. Then the difficulty would decrease and all hash power would move to Bcash and be mining multiple blocks per minute. Thus giving the miners more rewards quicker from mining Bcash. This slowed down the Bitcoin network because all the hash power moved to Bcash. Once the difficulty increased on Bcash and made it less profitable than Bitcoin all mining switched back to Bitcoin, and the cycle continued. It’s gotten a little better but miners will always follow the profit.
Charlie(LTC creator) knew early on that you couldn’t just compete for hash power against Bitcoin. So when he forked the code and created LiteCoin he changed the mining algorithm to Scrypt. SHA-256 is a very CPU(early on) intensive algorithm(it’s moved to GPU intensive and now almost exclusively ASIC chips) and Scrypt is a very memory intensive algorithm. So, the reason Charlie did this was so that you could mine both Bitcoin and LiteCoin on the same hardware.
