To do Monero properly you need to wait a while (at least hours, better days) while churning to other addresses, being sure to keep your ringsize and fees looking like everyone else's. Hopefully they will raise the ringsize minimum to 10 in the upcoming hardfork - that will go some way towards fixing the problem.
For now, I bet there will be cases of people happily bouncing to Monero via Shapeshift and getting busted.
My future freedom depends on me getting this right, so I am a bit sensitive on this topic. It took me a while to cut through the fluff and figure out how to churn enough to make it safe. Fortunately I also used multiple Bitcoin mixers on both sides and didn't originally get our Bitcoin investment in a way that's directly linked to any of our identities.
It is somewhat irresponsible of Monero's marketing to make such grandiose privacy claims at the moment. I say this as someone that loves Monero and thinks their team is fantastic, and I'd bet Monero will be the privacy currency winner if it isn't already.
Personally I can see someone obviously paying me in BTC. But I will only send out XMR. It's a one way street with me regarding BTC.
Time is going to tell wether we retain our freedom or not by betting on XMR.
