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?
It looks more like a EOS project and its history started quite similar.
I bet there was a private presentation among whale investors and they agreed on buying out a lot of DOT coins.
And imagine knowing that good project will start in X days/weeks before anyone, buying coins for $1-$2 and now its above $4 so at least 200% profit for those investors and we can see they're not cashing out just yet.
Until the day when they will collect the money, the coin will therefore risk falling? it is similar to Algorand the price was very expensive for an auction then the investors in sold their coins and the crypto to start to descend downwards
