I am an Ethereum fan and I also invest in Ethereum, but I saw Polkadot price increase very high and now Polkadot is in the top 5 on coinmarketcap, so in your opinion in the next 7 days, which price will increase very high? Ethereum or Polkadot?
if I personally would definitely choose Ethereum

For the next 7 days, the one that will go up is still Polkadot, although I personally also like Ethereum and am trading it right now, but as a percentage increase I think Polkadot will still be higher than Ethereum in the next 7 days.
