I've been running a cryptotrader algorithm with ongoing tweaking for a about 9 months - it's done me quite well considering we've dropped to a third of its starting price earlier this year.  If you haven't heard of cryptotrader and are interested in algorithmic trading - you should definitely check it out.

I've also been dollar cost averaging into the market with recurring buys twice a week since November.  Comparatively - my bot has done significantly better than my manual trades and DCA'ing.
