I still favour Ethereum to be honest. Stellar came out of nowhere. I have colleagues here who had Stellar on the radar some early stage all year already. Only thing I really see competing with Ethereum in the nearer future with regards to ICO is still Neo. Some say "ah EOS such a brilliant tech" but they are earlier stage and still have to prove a lot of promises. Talkiking about tech was willing to look on Nano so transferred my one BTC to Bitgrail and that was my only exposure exchange wise and bang most likely big part of Nano gone. I wont buy Nano again even if they should fly to the moon but in my experience better to focus on projects you are doing well with.
