Is it really necessary to stay under the radar. Do you feel like your rights are violated SOOOOO much that you spend excessive time using Tor ir i2p or freenet? I tried them out and honestly the deep web has been an underwhelming waay overrated experience. I want BTC to go mainstream because I'd like to see everyone pass on the savings of using BTC with lower pricing (yes a pipe dream probably not going to happen) and I want to see companies give kickbacks to users who use btc over other currencies (sort of like what isis is trying to do - they feel threatened by cryptocurrency so this is an attempt to keep users incentivized to continue using consumer debt attached to high interest rates.)
Not all BTMs require you to 'sell your palm print|ID|DNA|etc'. I think they do more good than harm because it draws attention from those who have no idea what it is and it makes those who DO know what it is smile because they see that cryptocurrency is becoming more accessible to the mainstream.
