In the end this means you would have to spent either 70% of the amount earned from free rolls on lottery tickets or wager 3.5 times as much in multiply assuming you have no bitcoins in your account!
I don't know how accurate your calculations are as it is difficult to keep track of your total wagered amount. You would have to start off with an account that has never wagered before to be able to do it.
I do want to point out wagered != spent
It's actually quite easy to wager many times your balance.
