Voting power is directly proportional to the amount of coins you own, so if you own 1% of the money supply your voting power would be 1% of the total votes, regardless of how many DPOS nodes you run.
Damn, I must have read 20 pages on the site, wiki, and forums with regards to voting and they fail to clarify that.
Ok, that makes it clear the difference between Bitcoin and BTSX and reinforced some serious dilemmas within BTSX:
With DPOS the largest stakeholders can simply vote themselves as delegates to collect a salary and control the approval of transactions. Stakeholders could try increasing the delegate quantity above 100 but that would increase costs and thus it is likely that they will settle for a smaller amount of delegates. With Bitcoin the amount of "stake" you own is essentially tied to the amount of hashing power your own.
Thus the health of the network is comparing the distribution of hashing power in PoW to the largest stakeholders in DPOS. Unfortunately, we have no way of knowing what the distribution ratio is in BTSX unlike with Bitcoin where we can see the accumulation of miners within pools and the quantity of miners and where they are located in realtime. A large stakeholder could make it appear that he is many users and make it appear that a fair vote exists. With PoW the expense of equipment and electricity decrease the value incentive of miners as it makes it very costly to conduct a 51% attack. With DPoS it would be much more costly if an outsiders tries to buy up a stake to conduct a 51% attack , this of course wouldn't need to be done as the existing stakeholders could "irrationally" attack themselves, or hackers could hijack the stakeholders, or a series of scams /ponzi schemes from grifters could slowly or quickly accumulate all the stake. A Mtgox scenario with DPoS is really dangerous (like with Vericoin) but with bitcoin Mark merely stole the coins and doesn't control the miners or nodes.
