The ETH profits were just my way to get the Hive needed for the investment.
In the game you can buy cards for 4 Hive or 800 SIM each, and then start building from there. What I did at first convert some smaller currencies I get from post and comments to SWAP.HIVE and then buying SIM.
Once your income becomes 800 SIM daily, that would mean you could buy a card each day from just the earnings from the game alone, instead of sourcing from the outside. But the extra boost always helps.
