Well if anyone of you actually mined instead of just playing this game, you would all realize mining is a random luck draw, sometimes you find a block in (using btc) 10 mins sometimes longer and sometimes even under 10 mins. Making a turn base game on something that is so random is like playing on a ice lake, one day your going to fall through.
Perhaps there's a way to reduce the randomness by reducing the blocktime and make 1 game turn every X blocks (e.g. block time 20 seconds, 1 game turn every 3 blocks)
In a RPG, 3d20 damage is also more uniform than 1d60...
There are other ways to fix it, too. For example, if some players issue transactions in one block, and some confirm in the next block but not all of them, the gamestate could choose not to update until all of the transactions are confirmed, giving each player an equal chance.
It could be done map-wide like that, affecting the base speed of the game. Or it could be done only for players in close proximity such that combat might occur, causing a bit of a time warping effect.
Overall, I don't see it as a huge problem to fix, and I think it will be, soon. Everyone just has to be patient
