Hi Andronicus. After I made that post, I had a bit of a think about it and realised I was probably helping myself more than the coin and other miners (as you rightly mention). So, I've now parked my miners on BTM for better or worse 
You can see me on xhash as ben96c - it's a long story why I mine under that name!!

Furthermore, your method for collecting a greater quantity of BTM than straight mining is also a perfectly pragmatic approach, for your desired outcome and not for me to criticise.
However, my simple outlook is that if all miners adopted the same approach, the yo-yo effect would be even worse. It is the consistent miners, like myself, who confirm the currency at high difficulties that you have mined at low difficulty and support the network whilst other miners switch to more easily obtained currencies and perhaps trade them to BTM.
