After a suggestion from dbryceman, I've modified the vote rewards to include a chance of getting in-game currency. This was something I did in the past, but at some point had to re-do vote rewards and forgot to include currency again. Here's the break down:
All players will always get at least 10 coins for voting, this is despite what other rewards you get. For all ranks, the odds of getting the currency reward is the same as getting XP Bottles (which is the most common reward). As a non-donor, the reward will be a random value between 10 and 50. As Neon or Steel, you can get 50 to 75. And as Platinum or Carbon, you can get 75 to 100.
Hopefully this'll bring currency back into play a bit, whether you want to buy a shop plot or just want to teleport randomly more often.
