I've been mining Electroneum since December. CPU mining on some dual Xeon E5 servers I built, the total hashrate is around 2000 H/s. I chose CPU mining as these servers could be repurposed if I decided to stop mining in future whereas high-end GPUs have no use to me.
I was previously converting these straight to Litecoin but I think it's way too late for this to be very profitable. I'm now keeping all mined coins in my Electroneum wallet and see how the price goes in future - they've been down to $0.03/coin for a couple of weeks now. The highest I've seen was around $0.20 for a short time.
I considered mining Bitcoins back in 2010 when it was easy but decided it was a waste of time and donated my CPU cycles to SETI instead. Probably not the best decision looking back!
