What if we could transfer crystals from one tanki online account to another. For example, you have two accounts (account 1 and account 2). You have 5000 crystals on account 1, and 0 crystals on account 2. You want to transfer 3200 crystals to account 2, so you can buy Mammoth M1. You sign in on account 1 and click a button that allows you to transfer crystals. A box comes up, where you type in the username and password of account 2, and how many crystals you want to transfer. Click the transfer button, and then account 2 has 3200 crystals, and account 1 has 1800 crystals.
