I have not been dealing much with PRL so far. What I understood, it is a protocol based on IOTA (and somehow also utilizes the Ethereum blockchain). Were the 70 million tokens distributed through an ICO? And what about the remaining undistributed 40 million tokens (according the figures of Coinmarketcap)?
According to a post on reddit, nearly all the coins have been mined and exist in the 12.1k wallets. I'm not sure what amount had been distributed via the ICO. Also note, that a coin burn of 10 million tokens is set for March 1st, setting the total supply at 98mm.
