You know dotcom bubble was the caused because people rushed to buy technology companies shares.but the problem was that most of these tech companies did not even have a product or even a plan to have a product.they were just in for the money they can grab.
I think this is a very valid comparison, but I dunno if BTC would emerge unscathed from an alt implosion. It's going to take more time for there to be a detectable difference in most minds. We can already see it developing with serious investors, I've never seen a talking head on TV enthuse about EOS or Cardano, but that still leaves a lot of little people to panic.
Either way I'm pretty amazed some of the stuff that's in the top ten on Coinmarketcap is still there.
I also believe that bitcoin will take a hit.That is why amazon is a good example in my opinion.Amazon shares dropped from 108 dollars to 8 dollars.But even that showed potential.Bitcoin price can go way down whether it is because of first mover advantage or just because it is getting improved way more that a flashy empty promise fueled alts but when the dust settles it will go way up than the pre~burst price.
