Non-Giftcard options for donation

Description of Suggestion: Current system only accepts Rewarble gift cards that can be purchased via 3rd party vendors, more options should be opened for players who wish to donate to the server. If anonimity is really the top priority of Kuro, Crypto(Monero) can be a payment option. Why Do You Think This Is Needed? Rewarble gift card comes with a premium when purchasing. That means if we wish to donate $50 to KuroMS, we have to pay more premiums on top of the $50 and we are not talking about a few cents. And there are reports where this is also inconvenient, for instance, 3rd party vendors may provide invalid keys that does not work, which again is up to us player to resolve that to get another usable key(or accept the money is lost forever). Possible Downsides or Obstacles: Loss of anonimity for Kuro. Additional Notes/Comments: If Rewarble is really the only option KuroMS is willing to accept, at least provide more DP per $1 to cover the premiums of these gift card.
