People usually make money from investments, not from currencies.
1BTC = 1BTC applies here.
If seen from a currency point of view, why would you care about the dollar value of BTC ?
Do you care how much your 1 USD is worth in CNY ? Currently 1 USD = 7.07 CNY. Wouldn't matter if it was 5 or 9 CNY.
Same applies to Bitcoin. It is intended as a currency. So the Donator and VIP's paid 10 / 50 BTC, regardless of the (USD/EUR/CNY/...) exchange rate.
That is genuinely the daffiest thing I have read all week, maybe the entire year.
I must set up a renewed Alpaca sock company and charge 60 BTC for a pair. When someone claims they find the price a little too high I will berate them with that reasoning and they will hand it over with an apology for not thinking like a true Bitcoiner.
I might forgive them and permit them to buy another pair for 70 BTC as a lack-of-faith tax.
