Thanks! As EOS is still in development stage, it's not possible for Bitspark to wait until it's finished. The EOS project looks promising however Bitshares at this very moment has the infrastructure , the liquidity and has been tested with four years being up and running. As mention by below is it likely Bitshares 3.0 will be merged with EOS eventually as Daniel Larimer (EOS CTO ) is still involved with Bitshares.
