I'm not confident in a coin in which the creators already threw in the towel once before. Time, resources, and electricity isn't free. This is no longer a worthwhile investment for me in this situation.
I did the same thing and understand exactly how frustrating it feels. I lost about 1000 bip which I got rather easily back then in about 2-3 days.
Still I decided to start again. Partly because the project seems fun but also because I can't really find anything else worth mining. I can't do eth and all the other cpu/gpu worth anything are sky high in diff.
This one is still solo mineable and I'm back at 800 after 48 hours. So I like to think it as 3 days of lost mining rather than a stupid urge to delete "useless" stuff that overwhelms me from time to time.
btw, difficulty is falling.
