This is a inactive project and coin that has not been active in the market for a long time.
The coingecko and coinmarketcap explicitly state that this coin is inactive.
There are no active pairs for PLAN currency trading.
The last Twitter post of this project is related to 2018.
At the ICO held for this coin, about 1 million and 700 thousand dollars of capital was raised and due to the short period of activity of this currency in cryptocurrency markets, it seems likely that long-term investors are faced with their worthless coin.
I have put all the cases related to the inactivity of this project with a screenshot in the photos below, which you can check.
