However, some of your own criticisms have been weak, re: "it's a ponzi because people can't cash out large amounts". You should understand that the largest stake holders can only ever "cash out" by doing private swap deals that don't move the market. The bigger the 'ponzi', the bigger the vested interest at the top to keep the value high and stable.
Actually I agree. My wild (not sure of course) speculation is their plan all along has been to collude with the government and will be rewarded for doing so. That doesn't mean the price will be spared a return towards 0. You need to think this out more deeply. The serious players know damn well they won't have anything lasting if they don't play ball with the governments.
Since the top stake holders have a strong incentive to act honestly, decentralisation is only needed during the initial adoption phase.
Destroying decentralization is not honest, it is selling out. And it is exactly what I expect them to do. A ponzi failure could possibly be a cover for making the transition to government control. It may be disguised as "proof-of-stake".
Similarly, in the beginning, the 'cost' of inflating the supply and promoting equal opportunities for participants (proof-of-work, open source code and generic PC hardware) is very important because it appeals to egalitarian ideals.
Exactly. Marketing. Deception.
Later, when the ownership structure has significantly evolved due to competition and mergers, at some point it becomes unnecessary and inefficient to 'allow' new competitors to mine blocks. The ongoing process of centralisation either wasn't thought of initially, or the story was that it's a bad idea. Alternatively, they couldn't predict how quickly the system would evolve from widely distributed CPU mining through to ASIC farms in a few strong hands. So Bitcoin seems to be accidentally stumbling towards a structure with a central issuer, but with vestigial proof-of-work that adds a tonne of dead weight.
Satoshi predicted all the outcome we have now. Read his early writings at the cryptography discussion group.
Fee collection, network costs, ddos attacks. Practical concerns with high volume transactions were probably not considered very seriously in the beginning. Say that the transaction queue is getting 100k hits every second, and most of those are bogus. So a spam prevention scheme is deployed whereby a proof-of-work puzzle has to be solved before a request will be accepted into the queue. This effectively creates a separate payment scheme to pay small deposits before placing the real bid for moving large amounts of money. See how the structure becomes multi-tiered? Map it out. Or... Don't map it out. Do you really believe that 2 heads are better than 1? Then leave some parts of the development up to an organic process of trial and error, just like Bitcoin is doing.
There are multiple possible designs. I am hoping open source wins over the alternative presented above.
Provide a convincing cover story. You know that story about a fixed supply of 21 million coins? That fearful creator who disappeared? The highly convoluted decentralised and trust-free structure, the Bitcoin Rube Goldberg machine, because centralisation is evil? It's a stroke of genius from a marketing point of view (assuming it wasn't all a hilarious cosmic accident).
Whatever alternative you promote, like:
--demurrage or perpetual inflation
--some element of centrally planned spending that covers more than just network maintenance.
--smarter inflation that dis-empowers speculators,
or some balanced combination, you'll probably find that at best you'll get a lukewarm reception (think: polite clapping) from a small number of pragmatic, reasonable people who stumble upon your idea. But you won't gain traction unless you rally some religious fervour to give your cause a kick-start and also give it protective padding against growth pains. You really need to figure this out.
Not every altcoin has to strive for instant recognition and a ponzi-bubble.
I see someone wrote that the altcoins have been rising faster in value past few days than Bitcoin. Didn't verify.
But of course, that hypothetical altcoin will have an ace up its sleeve, otherwise it won't be the one. You don't need to explain marketing to me, I had 1% of the internet in 2001. What slowed me down was losing 95% vision in an eye end of 1999 and being in surgeries and face down in bed for 1.5 years. The momentum carried forward on its own until 2001 when friendster was released.
Friendster started the friend-of-friend feature and peaked at millions of users. Myspace and facebook copied.
But I don't know why everyone assumes it will be me to create that altcoin. I am also writing to inspire others to compete to do so. You don't know whom I have shared my algorithms and ideas with.
