Hello giga,

Can you try to justify the increased upgrade price to us? As it stands, a BFL Single gives $0.75 per mhash, a gigamining bond gives $1.44 per mhash. That's effectively 100% markup over the very base model (which offers lower $/mhash than the rigs you use). With the coming of ASICs, an upgraded TERAMINING bond will be $0.13/mhash (giga market price price + upgrade), while a BFL Jalapeño is $0.04/mhash. As you can no doubt see, it has moved from under 100% markup to over 200% markup. That's quite a difference in value.

With the BFL Jalapeño being significantly cheaper and more powerful than the BFL Single, the investment (as well as risk) is lower, which makes buying your own ASICs a much more attractive option compared to TERAMINING. It's certainly much more attractive than a BFL Single was to GIGAMINING.

Just tossing my 2 bits in -- I'm still unsure of what I am going to do with my own bonds.

Thanks,

CAPEX vs CAPEX + OPEX?

OPEX isn't that much, especially when you consider 90% PPS. It's obviously impossible to determine difficulty when ASICs hit the public, but lets assume giga were getting 10% of current mining. 200ghash means he gets 20ghash. My estimates put him at 20-25kw at the moment. I'll round it up to 30kw at $0.05/kwh (of course, this is all pure speculation, it could be higher). That's about $1k per month in electricity, netting him a cool $1.5k per month to cover other OPEX. When you then consider that TERA's CAPEX cost for investors is 50% higher than what bonds are currently going for (compared to BFL prices), it just seems iffy. Of course, electricity/storage/air condition costs all go down with ASICs, which means OPEX will be significantly lower than what I have listed here. It just seems that giga would make a considerable amount from the initial upgrade fees, and have the 10% to cover all of his expenses (while probably pocketing a decent amount)

Also, I did my original estimates based on the 0.40 BTC upgrade price. 0.29 BTC should be a bit better. I'm still not sure if it is worth it with the 90% PPS.
