Ergo just came out in aug 2021? Is this correct?

I consider myself new to mining only been doing it about a year mainly been mining rvn, did btcz for a sec cause it was cheap and easy to get alot and also started and halved around same time as rvn( waste of time with btcZ) , then stuck to rvn When learned about white papers and what it was all about, didn’t want to waste time with ergo if its just short lived hype about new coin entry but have to say its making hella movement the kind i feel rvn should be making not some new unheard of coin and ask what gives?
