It's little funny to see that a lot of the voices that claimed impracticality of blockchain have disappeared within the past few months. To be truthful I think that good times maybe ahead of us but all it would take for these lowlifes to return is a crash after the next bull run.
Thankfully this cycle cannot repeat ad nauseam since we know that blockchain will go mainstream and once the profits roll in from the tech, they'll all be worshiping it blindly.
