Read the TKN white paper. It is a very different solution. TKN is itself a constantly growing store of value. Not to discredit Plutus, it very well could be a good solution too.
Plutus seems pretty worthless. (May pump on release, because hey it's crypto...)
With TKN, 1% of TX fees are indirectly given to TKN holders. Even a tiny fraction of the Visa enabled debit card annual market share of $7 trillion will make TKN very valuable.
With PLU 0% of TX fees go to PLU holders. Instead for every say $1k funded and swiped with BTC/Other, customers get up to $30 free PLU. So it seems like the PLU devs have a separate company making actual money from TX fees and PLU holders are just suckers that will have the free PLU dumped on them daily.
