What is somewhat different this time is that the barrier for entry was so low. Absolutely zero investment in capital equipment, meaning all you had to do was hang out your shingle (or announce an ICO) and SHAZAM! you're a player. And that's why this shakeout is more precipitous and deeper than other industries have experienced in the past.
But the consolidation mop up phase will most definitely follow.
I'm not so sure this is the same kind of shakeout. It seems like groups (most likely exchanges) have manipulated the market and viciously pumped it and then wiped out everyones profits. That combined with fraudulent ICO projects that didn't have a product and no real marketcap getting free money from naive
investors and then taking that money which they didn't work for and selling ETH and effectively BTC.
I'm not so sure we have seen the boom yet actually. Consider only 5% of Americans hold Bitcoin and there isn't even dividend paying cryptos yet or cryptos for companies.
Unlike automobiles money has similar utility to the internet or basic goods like electricity or water. Crypto is fast, liquid and can be used to notarize. Not to mention this stuff could replace the stock market eventually because it attracts international investment with relative ease. So as long as governments don't snuff it out (which it seems like they are actually interested in helping crypto move forward) then we haven't seen the boom.
