very simple create a clan with your main account, put clan tax to 5% then create as many noob accounts as you can and let them join in the account you've just created and then send credits to those noob accounts to level their skylab, level 8 is enough and send promerium to your noob accounts and sell them,,,,,,,, the clan tax will drain the credits of your noob accounts,,, and send the clan money to your main account...TAAADAAAHHHHH!!!!!! THATS IT...
imagine you have 1 clan with 50 members not including your main account and each of your 49 noob accounts have 30 million credits.. the 5% clan tax will drain their credits and you will have approximately 73,500,000 credits a day..not including your main account. create second clan and do the same..hahaha thats it.
But this is very boring, imagine you have to log in 50 accounts everyday...the good news is if your clan reaches billions of credits you can sell those credits for real money like 100 million credits for 10$.... :D
