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

We're both an Ethereum fan and holding some in my wallet. As part of the strategy of diversification, I think it's good for you to invest on it if you see the potential on it. Well, I think the basis and ranking speaks for itself because the rank that it was before is quite far from where it is today. But to know if the price will increase for the next days, we'll never know as it it's volatile and just like the questions we always answer for the same question if it will go high or down, no one has the correct answer on it.
