So zerovert really has a working implementation of zerocoin? Wow thats pretty cool. I have been looking for a zerocoin (zk-snarks) annon coin for a while. Good job.
Yeah 1 letter indeed and you mixed up one letter it should be "with" not "whit" you have to move that H from the second place to the last place. 1 letter can make all the difference.
You should take the advice of other and trade coins. Rigs are expensive and expensive to run and with rising difficulty ROI unlikely to happen. Take 300$ and buy the dark coins on the exchanges. You will get way more coins and no change in the electric bill. Seriously save you fiat $.
