Cryptocurrencies, the bubble?

Throughout the time bitcoin has existed, the term bubble has been associated with it. Recently, I came across this piece of news stating crypto currencies as a bubble. Here's the link: https://www.cnbc.com/2018/01/10/buffett-says-cyrptocurrencies-will-almost-certainly-end-badly.html

Below are some of my thoughts on this.

Cryptocurrencies is not the correct term here or rather a valid term to evaluate. They have now become assets, utilities and platforms. I agree that they may seem to be highly overvalued, but then you are evaluating them against fiat.

Take the fiat away for a moment and consider the utility-value that they have offered. Truly trustless currency/value transfer from one person to another was never ever possible in our history. Ability to store our data over a disturbed, secure network(Sia etc) at rates cheaper than even what the likes Amazon/Google can't provide, is nothing less than revolutionary. Further you can earn for your spare space on your hard disk and similarly golem allows you to share your CPU. Ability to transact with no fees (iota) no matter how tiny the amount is, we definitely need that if the machines are going to use other machines as services in the future. Platform to create your own token (ethereum, Neo , stratis etc) and the ability to build distributed apps over it. And then we have steemit, social, indorse who increase our value using our data. Even if this is all a bubble in terms of fiat valuation. There is no way all of that utility value is going away. I'm personally willing to bet on that.

If we refer to the dot com bubble, all the companies lost their valuations, including Amazon, eBay, Qualcomm etc. But the ultility that they provided allowed them to survive and even go past their peak value during the bubble, in due time.

Unfortunately, all of that has been clouded by the hlod and lambos crowd. The crowd that is in for gaining fiat. If your are one of them, get out of this as soon as you achieve your target profit. You may not endure what comes after the bubble bursts, if at all it does.

To add to that, public address, private keys, offline wallets, GAS generated, tokens, contracts aren't really for an average common man to understand. But hey, so wasn't the concept of having a login id and password, selecting a product from a website hosted somewhere and further paying them using your bank account credentials on a mere promise of getting that product delivered to you at your door step, 20 years ago! One on hand we could sightly improve the technology on the other, we need to educate people and give them some time. Once they start seeing the utility, they will take efforts to learn it

If I have to send money from one country to another, I have to pay taxes/commissions to my bank, my government, the reciever's bank and his government. Don't we want a change here?

We have a global experiment going on here. And currency and bubble aren't the terms adequate to define it.
