I got a really good question in one croatian forum.
What will happened with part of gold of lost coins (for example lost wallets)?
Suppose that 5% of coin will lost, what will happen with 4% of gold (0,8*0,05=4%)
Ok, what you all have to understand that backing up, and minimal buyback price means that these things will happen at the worst case scenario only!
Let me explain: When everything will go according to my plan (best scenario), I can sell the premine and get at least 100 BTC. From that 80 BTC will be the amount I can buy Gold for. The Gold will stay in the Gold Account, publicly known, can be checked 7/24 at a website (not GoldReserve website, but the account provider's webpage). Minimum buyback price calculated and shown on the GoldReserve webpage. In the meanwhile, during that time, people trading GoldReserve and hopefully, as no other coin has a backup like this, price will be much higher then the minimum buyback price, so Gold will be sitting on the account, and giving an assurance to investors, traders.
Now. Back to the question. It is irrelevant that people might loose their wallets, coins. I have to calculate with the maximum amount of coins, because I have to prepare that price for the worst case scenario, when all of the sudden I have to buy back EACH AND EVERY coin and no one lost any of them!
Gold is only the assurance that your investment will not go down to zero! And that is a HUGE advantage, I can tell you that for sure!
