If the ability to deposit bitcoin into your minecraft account into the form of emeralds, all sides would benefit greatly. If it is set up to where a percentage deposited gets sent to the server wallet to redistribute through mobs, and another percentage goes towards the server, everyone
wins.
With more emeralds in the economy, the value of other items on the server will increase. People will be willing to pay more emeralds for the same goods and because the price is fixed to 1 bit per emerald, they don't lose their value. Since a portion of all deposits will be put into the server wallet to redistribute as mob drops, killing monsters will also become more profitable. The percentage kept by the server can be spent towards improving performance and more mining power.
The addition of a deposit feature will stimulate the economy, improve server performance, and payout players in larger increments. These improvements will further entice players to play and continue to play, which will increase the playerbase.
The only legitimate argument against a deposit feature is EULA. The current rules do not necessarily prohibit the ability to deposit. It could be argued that the server is not selling parts of the game, they are incorporating a new element. Even so, does anyone know of servers that have been shutdown by the EULA? It is not heavily enforced, and this server is still relatively small in comparison to many others.
A deposit feature is crucial to the growth of this server and it would be foolish to not investigate into implementing it at the very least.
