Many of us have asked the same question: why have nearly all of the donors and VIP donors who gave 10 BTC and 50 BTC respectively stopped using the forum.
(edit)You are right about the low price of Bitcoin at the time it was donated, it did take brave decisions regardless of whether the donor mined or purchased the BTC. There were 115 donors and 38 VIP donors. The VIP donors gave 1900 BTC where as the donors have 1150 BTC therefore that is 3050 BTC in total.
How much of that remains? What does not remain, where was it spent?
True, the price was low at the time, but it was still a valuable item, and given the buzz and promise of bitcoin, everyone knew that in a few years it would be more valuable and in high demand, yet these people had the courage to donate to the forum. Even if the price was so low or if they mined and obtained BTC for free, it takes a brave mind to donate as much as 50 BTC. They still deserve to be appreciated because they made these donations for the benefit of the forum, demonstrating how much they care about and support the bitcoin community. What i don't understand is why alot of them seem to have disappeared from the forum, what could there reasons be?
