Everyone focuses a lot on the "technicals," of crypto, which makes sense since it is entirely driven by speculators at the moment and fundamentals don't come in to play. But the fundamentals require analysis, because in the end - things really only last long-term because of fundamentals.
BTS is essentially a non-profit, it does not generate any value on its own. It pays for network security with dilution and transaction fees. The intrinsic value of a bitcoin is the marginal cost to produce the block divided by number of bitcoins paid to the miner per block. The number of bitcoins paid to miner via reward is decreasing over time, but will reach the floor of transaction fees, which is a variable. The marginal cost to produce a block is also a variable depending on the collective power of the miners (i.e., network difficulty), miner computing efficiency ( hashes/sec/(W*electricity rate) ), financing/depreciation of mining hardware, and development costs (since miners are the sole players with network financial incentive to maintain the code). In theory, if prices drop, then people turn off miners until the new network difficulty-price equilibrium is reached. There, therefore, is a minimum value to bitcoin (namely, where is the cheapest electricity in the world), but no maximum value besides speculation. There is no reason why a bitcoin should be priced anything except for the minimum, besides speculation.
BTS is different, as it is a "for-profit" coin. Real companies that produce goods and services and list on the network (with true regulatory compliance), which collects network fees. Fees pay expenses (technology development, marketing, business development, network security) and return a "profit" to the network via burned fees. The value of BTS is in the earning rate, as it is in a normal company (price per earnings ratio, for example, which is always "infinity" for bitcoin). If you can you estimate of the bitshares return and risk -- you can actually price BTS. The game is then trying to be the best at predicting return and risk.
That fundamental difference is why I've come to support bitshares.
But this was also my concern with BTA2.0: how do I price a short to create BitUSD when I know the floor is enforced by the network (the peg), but there is no explicit mechanism for enforcing a ceiling? I think the answer is in the expected profit from BTS. As long as BTS produces profit (my projections of earnings of BTS exceeds the current valuation), I'd be willing to leverage what I have to get more of them. So I price at a discount because I don't know what liquidity will be like when I sell and I want to account for it. There then becomes an auction on willingness to accept liquidity risk. Market makers profit from liquidity risk (over the long term), and also inject liquidity in the market - so I feel like the system has a good chance of working...
