indeed the real key factor of the success of the IEO or ICO aside from the exchange and the team that played a role was the product of the project that was launched. if it's good, it's certain to have a bright future, including this 2KEY
Nothing is certain,,, you have for sure to have a good team and good product but more importantly a big community of users who really like the product and are using it a lot,,, which I guess is what 2KEY has. Tried it myself actually but did not like it. I generally hate anything with ads and more than 1 step to get to my link!
