At the moment I am simply buying bitcoins through LocalBitcoins and then transferring it over to my Evolution account. I am using this for small orders of Weed and only buying about £30-40 of bitcoins at once and then spending it almost immediately. I am not hoarding them and waiting for a fluctuation in the market. Am I being safe enough or should I be adding levels of encryption and tumbling? Please upvote for visibility.
