Checked on Alphabay to see how Monero is doing there. Its not even begun and there are 75 pages of items from sellers that accept Monero, lots of them are accepting Monero ONLY. No need to brag any more, image is worth a thousand words

"ONLY ACCEPTING XMR AT THE MOMENT"
*economic singularity intensifies*
This is quite a development among sellers. I would have thought that they would switch slowly to XMR instead of doing it right away.
I have a question. Let us say I am a seller in the darknet. I now hold XMR in my wallet and would like to cash out some into BTC. So I transfer some to Shapeshift. Will my transactions be traced by snoopers online?
What would be a secure, anonymous way to trade XMR to BTC online?
