Cryptos are still a long way to go in terms of evaluations for it to be compared to the dotcom bubble occurred in the late 1990s. So first off there is a still a long way to go. Second even if it is a bubble it doesn't matter. A healthy purging is always required to separate the grain from the chaff. The same happened in Dotcom bubble as well. We had some amazing companies like Google, Amazon et al which pretty much changed the world we live in.

With blockchains we have the added advantage of transparency, distributed decision making and the gains are shared by a large number of common people unlike the limited set of investors during the dotcom bubble.

So who cares if it is a bubble or not as long as you are investing in the good companies for the long term. I am suggesting all my friends to invest in Cryptos as an insurance against the failing governments and FIATS.
