I'm from Europe. Don't mind my low knowledge about everything that happened in the West America during the Gold Rush. I'm using it as a metaphor because after the Gold Rush, California prospered in other ways. Gold Rush is in this case - blockchain going mainstream and let's get that California smaller to Los Angeles. Yes, some cryptos will die during it, some will rise, but eventually many will settle in comfortable climate of the mainstream blockchain. Thanks for your response @somethingsubtle
