I personally might choose to have Ethereum and Eos because I prefer to use these two coins to trade so that the assets I have can be very much from the benefits that I get from owning these two coins.
the two coins will certainly last. I think it's only a matter of time until the two coins compete tightly. I think, the development of EOS has also been quite good, even some projects have already used this platform. well, but so far, ETH is still better in my opinion.
