And I wonder what will be when all BFG are mined, holding is unprofitable and token price does not change much.
From the look out of things, don't you think their team will be adding Liquidity to increase the token price in time soon?
Add liquidity to what and how will that increase token price? If you're talking about opening up farming again, I don't think so. They will most likely let the players mine the remaining tokens through in-house games and slots. If it's about adding to the reward pool, maybe that will increase interest on the token but I also doubt they will implement that.
I feel like the dividend itself is good enough, because people play with BFG as well, and that means there will be some (many) who will lose their BFG and others will earn it too, by staking BFG basically. That's not a bad idea and I believe that people should be focusing on something that will be profitable if you hold it long enough, not when you do something with it.
If you think that BFG price itself will go up then you think it will go up and there isn't anything else you should worry about. If you believe that it's not going to be easy, and it will be a bit of a trouble then it is going to be a bit of a trouble. Just think of the price, not the staking part.
