there is a MASSIVE daily usage if someone can formulate the perfect peg;
electronic $, cny, euro, gold, silver ... that can be moved a 1000x cheaper than traditional system ... possibly bigger than BTC in terms of actual usage in daily life.
coino (nxt) + nubits (peer) have failed.
there are still 2 serious contenders left on the field, and if plenty of recent 2.0 ready to take to the field also.
critical issue is the "upside" ... an honest peg system ... likely would be able to provide roi @ standard bank rates ... which is not appetizing to the general crypto investor
