"Get educated" is the best advice anyone can give a Newbie here.
Right now, we have big name in online retail and wholesale, some banks and other financial institutions accepting Bitcoin as well as other cryptocurrencies. I don't know about you but to me that's a signal that this craze is real.
I'll challenge you a bit only on who's accepting Bitcoin. I don't think there are really big name online retailers or wholesalers accepting Bitcoin. At least I don't hear of any progression or growth in acceptance among retailers and wholesalers. It's shocking, really. Bitcoin is becoming less and less of a currency and more and more a store of value.
That's what it looks like to this noob. I'm finally paying attention but for now it seems like more of an investment than a currency to be used on the daily. But I look forward to the day that when it's mainstream and banks no longer get rich off us.
