Why havn't you jumped on Ethertanks yet? This has only been around for 2 days, you will be an early adopter. This is guaranteed EASY profit. For every tank bought you will get a dividend, and the tanks value will go up. On the 7th you will be able to sell you tank at a profit! It's literally impossible to lose money on this. I recommend buying the LT-1 Tank as it is the most popular so you will get the most dividends.
On the 14th you will be able to battle, and their will be ETH rewards. Therefore increasing popularity and increasing your gains.
You missed Cryptokitties do not miss this, hurry and get in before the normies do.
