Would it be bad to use Monero just to buy clean coins for use on markets?
For instance, buying Coinbase --> BTC to Monero (Shapeshift) --> Monero to BTC (Shapeshift or another service)
And then just using like this?
Just trying to be as safe as possible.
Use xmr.to because they send clean BTC. Coinbase>shapeshift>your xmr wallet>xmr.to=clean BTC with no association to you.
