I would like to have your opinions

https://polkadot.network/Polkadot How does this crypto coming out of nowhere appear in 7th position even though it was in 5th or 6th position when it is currently going down? it's a Pump and dump.
Or is it a crypto that will one day be reliable with a good future

is it a standalone crypto that has not been launched on ethereum?
Polkadot is a very popular cryptocurrency for now, because Polkadot makes a very good and useful project for the future, so people are interested to investing in Polkadot for the long term and I am also interested to investing in Polkadot for now, because I think Polkadot is a very extraordinary project, so it makes the price of Polkadot can increase very high and enter the top 10 on coinmarketcap, therefore I think Polkadot is not a scam project.
