Welcome to the 90 percent. Not everyone succeeds, and your next venture will be dependent on your appetite for risk.
It could be a factor of timing, too. In 2012 there was a startup for everything. In 2014 there was an app for everything. In 2016 there was a blockchain for everything. In 2018 there was a decentralized app for everything.
Pioneer advantage is no longer an assurance of traction. It’s more of value created for customers and the ecosystem.
But that’s just my opinion and observation.
Good luck on your next venture!
