forget about bitcoin to buy drugs, go for pot

being serious, there are better options now. no need to mix coins, just go for some anon coin like xmr/shadow/nav
Most of the dark markets accept only Bitcoin. A few of them may accept Litecoin or Ethereum. But I don't think that any of them accept these little known altcoins suhc as XMR and NAV. So it is not possible to buy anything with these coins.
On one market some vendors accept Monero in addition to Bitcoin.
Litecoin or Ethereum, accepted right now on a DNM, where?
