Pluton are a digital Ethereum asset that is issued automatically to users of the Plutus app as a reward for using the Plutus Tap & Pay app (making payments with Bitcoin or Ether). The payment process occurs via a proxy conversion to a virtual debit card linked to your account.
Plutons are also an optional way of paying for goods and services, just like Bitcoin and Ethereum on the Plutus app. The advantage of using Plutons instead of Bitcoin and Ethereum is that there are 0-fees and near instant transactions.
There is only a small (4.25%) amount of Plutons (850,000) available for initial distribution. The reason for this is simple, they are designed have a valuable and unique use case — to pay for everyday goods using the Plutus app. As a result, they are rare tokens with a real life use for NFC payments.
