EOS will have very big development prospects in the future. I think that investing in EOS will be a very correct decision. But i think not agree that EOS will surpass Ethereum. I also don't think EOS will be widely adopted as Ethereum did and i have 66 EOS in my balance , i hope i lucky

As for I am not holding EOS because I believe in Tezos project greatly. I think that it is much better and have many improvements EOS dont have.
