How to protect gold from ban?

[Mxvx]

Hello, I wrote a small mouse macro to farm about 100000 gold a day, with one account.
My question is, how do you store your gold so that it is not affected by the ban of the account?
Is it usually enough to create a second battlenet-account, invite both of them into the guild and store the gold in the second character's guild bank?
Both accounts are operated with separate IP addresses.

Thank you for every tip and sorry for my english.

There is not really a way to protect your gold 100%...
