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

I have always been a fan of Ethereum but as I have seen the capability of Polkadot, I have just made a decision of investing in it as well. I could feel that it's good for a long term hold. I'm still searching more about it and I'm still learning about its possible movements. I guess we don't really have to choose one because both are worth investing in.
