yes you are right, even Polkadot is not only worth it to discussing, but to be invested in the long term too, because I believe Polkadot is the one of altcoin that has the potential to be able to provide a big profits in the future, because the price of Polkadot will continue to increase and of course Polkadot will be more popular than ever, so this is the right time to buy Polkadot, because the price of Polkadot is going down (correcting), so the profit you get will be even bigger if you invest in Polkadot at this time, because you buy Polkadot at a low price.
