Again I don't know the specifics about the hash difficulties and if it was programmed to do this from the outset, but getting one hundred thousand percent returns in a matter of years is not in any way sustainable or good for the future of bitcoins.
I understand the technical details of how the currency works. I will try to answer what can be done. First, you must grasp the distinction between:
- Bitcoin, the technology properly called Nakamoto proof-of-work chains,
- bitcoin, lowercase, the currency ("BTC") based on a particular proof-of-work chain started in 2009,
- the block acceptance rules (monetary policy) implemented in the software used to extend a given chain, and
- the network of computing resources ("mining" or "hashing" community) working on extending a given chain and, in the process, protecting its transactions.
The technology can be trivially used to start new chains (even for non-financial applications as
detailed in the wiki). I have written in favour of starting a new chain with a policy similar to BTC's except for a much higher minimum difficulty. ("Minimum difficulty" is a parameter of Bitcoin monetary policy.) The new chain would result in a currency (herein called "BC2") functionally equivalent to BTC and competing with it but lacking the overhang of early wealth that concerns you.
BC2 would face several hurdles to acceptance similar to what BTC has overcome versus older national and digital currencies. However, it would be based on a more proven technology than Bitcoin was in 2009, and the technical barriers to its adoption as a BTC alternative would be slight. For example, once critical infrastructure supports BC2 (Block Explorer and MtGox, or something like them, come to mind), merchants, miners, and pool operators would have only to repeat the steps they took to support BTC.
It is hard to discuss this proposal in the forum, because most users oppose the idea, and many put it down to "jealousy". I do not presume to know the motivation of any particular BC2 opponent or opponents in general, but one reason may be that they have a lot of BTC, want to profit from the continuing rise of the BTC price, and fear that a competitor could derail this plan. Or perhaps they worry that a second currency will confuse the public and threaten the technology's acceptance. Some may scorn the idea as a plan to punish the Bitcoin pioneers. I consider objections on these lines baseless. As I see it, a currency like BC2 would make an attractive product in comparison to BTC, and the potential value of all BTC (in a rational market, if such a thing exists) is inherently limited in a way that would not apply to BC2. (Look up Forum user
unk's posting history for some eloquence along these lines.)
I doubt that most Bitcoin users are aware of the situation, let alone how it came to be. (BC2's chance of success would benefit from spreading this knowledge.) Please look at Sipa's graph of difficulty and network hash rate over BTC's entire history:
http://bitcoin.sipa.be/speed-ever.png. Difficulty was at the minimum (because few computing resources went to mining) through nearly all of 2009 and didn't really take off until July 2010 (with the advent of GPU mining). During those first 18 months, when the project could at best have been described as experimental, 65000 blocks were mined. The "work" expressed in those blocks' hashes would get you perhaps about one block at today's difficulty.
This would be no big deal, but for certain of Satoshi's monetary policy choices, which the early user(s) supported by running his software. Namely, the 50BTC reward for each block (constant over the period in question). This fact of policy translates into 3.25 million BTC earned by whoever mined those 65000 blocks.
Satoshi could have chosen another formula for bitcoin creation (without having to abandon the deflationist principle or the 21 million bitcoin limit). He could have chosen a formula that would have slowed money creation to a trickle while difficulty (more precisely, network resource growth) stagnated.
Some people may look at this and conclude that Satoshi designed it this way to obtain a lot of bitcoins for himself and his friends. I don't see it that way at all. Taking Satoshi at face value, I think he expected the climb in network hash rate to occur 12-18 months earlier than it did. I think he did his best to promote both the technology and the currency before and after he started the chain, and it is really a matter of chance that it caught on when it did and not earlier. Going out on a limb and giving Satoshi the benefit of the doubt, I think he is disappointed that it took so long, even though an earlier widespread adoption would have left him with far fewer BTC. In other words, I think he and his fans wanted most of all to establish the technology for the benefit of humankind, and that amassing great wealth was, at best, a secondary motive.
With all due respect to the amazing thing Satoshi and the team have created, they have not been backed by a large budget (at least until recently) and have left several loose ends to be addressed by stakeholders once the system grows. For example, ambitious scalability improvements have been
proposed but not implemented, not even in a proof-of-concept. The simplicity of the
total BTC curve has more to do with Satoshi's time constraints than elegance or popular appeal. To the list of loose ends, I think we can add the need to create a stronger block chain.
How best to do that is a question I've worked on and discussed a little in the forum, but I will leave it for another post.
