It is in Python. Not a language of choice for me, but there was already a working reinvesting bot in the CEX.io forums and I rebuilt that into what I wanted very quickly. I'm slowly cleaning it up, but I built in 3 different bots in it and the third one I've modified many time. The first two bots were losers.
I don't have any plans to share my bot though. That can be a huge amount of pain and I expect to keep in a state of constant tweaking. Frankly, I think any bot that is just shared, probably isn't worth much.
That's just what I did to grow my Ghs over my first month of cexio.
Bot v1 sells all BTC & NMC for GHS every hour
Bot v2 sells % of NMC and % of BTC every hour
Bot v3 is being fine-tuned to be distributable for easy git pull so cexio mining newbies can reinvest with no effort
Bot v4 might do something like only sell by placing orders just above/below the price at time of sale, who knows.
It's pretty much usable so if anyone wants it PM me
Have you done any analysis to see if the value of your holdings is decreasing or increasing?
