I think I found a way to recover my spreadcoins but you may not like it.
As I lost my wallet.dat I don't know exactly what blocks I mined and exactly how many coins I had.
I can approximately determine block before which my lost coins are situated. Everyone who have mined coins before this block will send them to him/herself (this can be made automatic). This will mean that this coins are not mine. Then, using some hack and releasing a new client I can send myself amount of the rest coins (or maybe less, say 80%).
This rasises two concerns:
1. What if someone will forgot to send coins to him/herself? These coins will still be spendable so he/she will not lost them. This raises the second concern:
2. What if I am a scammer and want just to double my coins, keeping old ones and getting new ones? The only way to prevent this that I see is to limit the percentage of presumably lost coins that can be spend but this is not trivial.
What do you think about such a plan? Is it acceptable in you opinion?
P.S. This way there is no need for anyone to donate coins to me.
I do not know how you can acchieve this, but it seems like tampering the blockchain.
This method I would use only as last resort, because it lowers credibility of the developer/coin.
What if such developer will decide to make something similair later?
Consensus is not the best tool to decide, as there still may be minority, or significant amount of users which will be harm with such decision.
Maybe these are the reasons why this attitude is not considered the best.
But now the blockchain is really young, and there are not financial operations, just mining, so perhaps we can excuse it.
But, what solution is the smallest evil, depends on the amount of the coins owned by the developer, or, the ratio to the amount of all existing coins. If developer holds very significant amount, maybe around a half, then another solution - the donations - may not be feasible. But if the amount is say one tenth or maybe one fifth of all mined coins, then I think the solution by donations is much cleaner.
I am willing to donate one fourth of mine coins. I have mined it with all my CPU power accessible for more days, when my hashpower was significant compared to the network hashrate. So the donation is significant.
