NEVER listen to a Monero shill.. you will go broke

As usual, you are ruining some good points by going too far off into hyperbole.
Investors in Monero (at the liftoff point when I wrote to buy it, after the initial nosebleed bubble ostensibly caused by Risto) have done very well.
However, presuming that Monero guarantees your untraceability from the authorities is not going to end well for those dumb enough to believe that.
The technical reasons have been covered ad nauseum in the past by myself:
* Sybil attacks on anonymity sets
* Meta data correlation (such as IP address and browser fingerprints, etc)
* Combinatorial unmasking of anonymity sets (I had to fight with both @smooth and Shen-noether about this)
* Rubber hoses (even against those you transacted with)
But you make a good point. Polo is a single point of failure. Hint Hint...Bitsquare.io
* On/off ramps
