But now that we have widespread adoption of smartphones and high-speed internet(still lagging behind in some countries), plus a plethora of tools to build apps and track, analyze and influence user behavior, tech companies are some of the wealthiest and most influential enterprises on the planet, two of them even survived the 2000 bubble(GOOG and AMZN), IMO, far beyond the imagined potential of dot-com predictions.
So I partly agree with you, I think there are some extreme expectations on BTC and a major crash seems possible, but who knows, maybe technology will enable BTC or some other cryptocurrencies to thrive the same way the internet recovered from the dotcom bubble burst.
One can only hope this will be "the next" .com bubble -- there will be money to be made. Given the amount of liquidity that was pumped into the market by the fed, it will be interesting to see what stops this train.
The more and more you look around, money isn't worth anything anymore. Like that recent Leonardo Da Vinci painting that was sold for $450m. Assets and companies selling for a 10-12x multiple, excessive property prices in prime locations, etc. Asset prices have been driven up significantly across the board.
Transaction costs are high, Transactions take forever to pass, and it's not even really anonymous.
So what's left but a token that has no underlying value other than a proposition which can largely be discounted?
