To put some perspective on TQS... Viva will quickly be at it's peg of $10, and TQS are currently selling for 10 Viva. Currently you can buy both for less money, but I don't expect that to last.

As @eirik mentioned, there will only ever be 100,000 TQS, and under normal circumstances, those 100,000 TQS will share in 20% of trading fees. That means that for a TQS to pay for itself (at $100/TQS), Tradekwik will need $50M in trading fees. At the current fee of 0.5%, that translates to $10B in volume.

$10B sounds like a huge amount, but keep in mind that NYSE does 2x that volume every day. The global foreign exchange market does that volume every 2 minutes and 43 seconds. As I write this, all crypto exchanges are doing ~$3B per day. That means that for a TQS to return 100% APR TradeQwik needs to do about 1% of the current volume of all cryptos. With the stuff that's on the horizon, that doesn't seem an unreasonable goal.
