Of course, there is no exact data. Now every coin tries to look better. Each coin is good in its own way. I have more confidence in Ether
Is there any data behind the reasoning that EOS has the biggest potential to overtake Ethereum aside from the free transactions? There are so many next gen blockchains like Wanchain, Rchain, Icon, Cardano, Aion, Matrix or Zilliqa and It feels every other month we hear about another candidate to throw Ethereum from the Throne. Why EOS?
You are right. As you mentioned already tons of projects are planning to switch over from ETH. It would be interesting both EOS and ETH. A number of community strictly compare to EOS with ETH. Everything is possible basically, wait and see. For me, EOS is plenty hyped though.
