I'd like to dip/anonymize my BTC holdings into Monero and then right back again to fresh BTC addresses into long-term cold storage no one can track from previous BTC addresses on the blockchain. I don't have a lot of experience with Monero and am wondering the best practices in doing this.
Seems like washing your car in a dust storm, but you could do something like this:
Deposit BTC to a high enough volume exchange that supports Monero. Transfer Monero to alternate exchange (or just trade back on first exchange, if you are not sufficiently paranoid), withdraw BTC to chosen wallets. Repeat each time you do a BTC transaction. Or just use Monero. You will eventually, so just get ahead of the curve.
