well, so far, I see the development of polka-dots really amazing. Even now it is still in the 4th position of CMC, so I think it is a coin worth taking into account when it comes to investing. however, the price is still quite cheap, I think that the price will increase in the future along with the development of cryptocurrency. but I'm not sure that polkadot can outperform ethereum or BNB.
Look the price of DOT might never cross or reach as much as ETH because of the simple reason that the total supply of ETH is 114,786,596 while the total supply of DOT is 1,047,480,258 which indicates that the price of DOT should realistically be lower than ETH because the total supply of DOT is like 9-10 times of Ethereum.
Seeing the polkadot ecosystem and the improvements that the team has been putting into work, I see that polkadot got a bright future.
No doubt about that and with the current clogged Ethereum network which has caused fees out of control, its almost a guarantee that Polkadot will do good in coming time.
I have some DOT with me which I am positive about but I will never consider the value of DOT reaching anything close to Ethereum unless something crazy happens or DOT becomes just too useful.
