thanks for your help guys. Ill try chipmixer but i dont really understand how it works.
I want all BTC in another wallet at the end of the day... can i just import the private keys in my wallet?
You get a link and deposit address, where you send your Bitcoin. Then you get, depending on your choice one ore more wallets back including addresses and keys. Read carefully the instructions on chipmixer and keep your browser open. You don't provide your private keys, but send your funds. But (hipmixer gives out whole wallets (without transferring) for that amount you deposited.
