If you meant fees incurred to convert BTC to USD to my local currency, yes. It was part of the forex calculation accounting for likely declining USD value. Basically for my electrical costs, it would take 3 months at constant btc value, difficulty and forex to break even. But since it doesn't, even if only difficulty goes up by an average of 4.5% every week, I'd never break even because electrical costs will definitely go up in the next 24 months.
