there are 1,36M minable coins per year, with assumption of zero rise in difficulty (difficulty rises because there are more than 2016 blocks in 2 weeks) and with assumption of zero fees. Also - selling business uses coins that are already mined. Stop spreading bullshit, please.
1) Sorry if ~1M was too inaccurate. 1.36M it is.
2) There is nothing to suggest that fees will be a substantial part of the equation. If fees do become a substantial part of the equation within the next couple of years, it will probably be because Bitcoin has become mainstream, and AM will not yet be ready to compete with companies like Intel or IBM if that happens.
3) "Also - selling business uses coins that are already mined" - I'm not sure what this means. If you think people are going to intentionally buy hardware at a loss, you're kidding yourself. Using a hardware sales based business model REDUCES potential revenue.
If we assume the simple model that AM attains and maintains 20% of the hashrate for another year, at an average of 75% margin (excellent and unlikely, in my opinion), drops to 30% profit margin (still maintaining 20% of the hashrate) for the year following, and to 20% margin for the next 8 years (again, at 20%), this is the breakdown of total BTC profit (remember that the block reward halves in approximately 3 years, then again approximately 4 years after that, and again 3 years after that):
Year 1: 0.2 * 0.75 * 1.36M = 0.204M
Year 2: 0.2 * 0.3 * 1.36M = 0.0816M
Year 3: 0.2 * 0.2 * 1.36M = 0.0544M
Year 4-7: 4 * 0.2 * 0.2 * 1.36M/2 = 0.1088M
Year 8-10: 3 * 0.2 * 0.2 * 1.36M/4 = 0.0408M
Net profit, ten years forward (reasonable estimate of fair market cap for most companies): 0.4896M BTC = 489.6k BTC
Current market cap: ~2.25 * 400000 = ~900000 BTC
Market cap at my price target of 1.5 BTC: 1.5 * 400000 = 600000 BTC
So you can see I'm actually modestly optimistic.
This model excludes transaction fees, as I believe they will either be negligible or accompanied by stiffer competition. You can adjust it with your own projections if you desire.
