I believe cryptocurrency is not a bubble and here is why. In 2010 tech bubble burst, the market cap is so much more than now and you consider the inflation these 20 years, it is so far before catching up to that valuation. And also many people around us still dont know about this.
Feel people confuse fluctuation with a bubble, Would say its more like an ocean and waves some are high and some are low. As with btc we have seen it go from low tide to 20' swells back to low back to swells. ETH is on the up and up still imo, Heard they recently picked up a contract to cover a companys smartcars network
I believe the same, because it is so distruptive technology that from long term view I will blow the market.
