yep, agree.
in 10 years' time, the cryptos that still exist on various blockchains will probably trade against each other quite stably like the yen vs the dollar (up/down 5-10% in a year).
and in 10 years, someone might look at a 10 year chart and exclaim: "wow! during that 'gold rush' in december 2017 my cryptos were worth 100 times what they are now" (ex: $200 bitcoin).
