Companies are different in comparison to commodities though. That said, you're right -- it is still early, and people aren't exactly sure how much exactly these things are worth. But part of the value derived comes from having a network of people using it.

If tomorrow you owned all the gold in the world and no one would be able to get or buy more gold -- that gold wouldn't be worth much.

Wouldn't it be worth a lot because you cornered the market on it?

I agree that gold is impossible to value (at least, the current valuation is impossible to justify). I always liked this argument by Buffett: http://www.businessinsider.com/buffett-on-gold-2012-2

But for bitcoin the situation is much worse. Gold would still be worth something. It is a physical object, a collection of atoms with some nice properties. It has industrial uses and the bling-bling factor wouldn’t disappear. If anyone needs or wants gold he would have to mine it, an expensive thing to do, or buy it from you. You could always sell it marginally cheaper.

Anyone could easily come up with an alternative cryptocurrency and what advantage would yours have over the others?

I can follow your reasoning, but: 1) just because something is digital does not make it worthless, 2) those gold use cases are really exaggerated when it comes to price setting. Gold derives its value mostly from the fact people say it is valuable, not from jewellery and industrial purposes.

One way to think about it: you have video games. There are marketplaces where people can buy and sell digital skins / clothes / gold etc. Every year, people buy and sell for more than $50bn in digital goods through these marketplaces. Ten years ago, I sold a top notch World of Warcraft character for a sizeable amount of money. Are all these people crazy? Maybe.

But how is value of these items set? Supply and demand and network effects. Why did a World of Warcraft character sell for €10,000 easily 10 years ago, and now it goes for a fraction of that? Less people are playing the game.

The same applies to cryptocurrencies -- you have two major cryptocurrencies: Bitcoin and Ethereum. Bitcoin has limited use cases, and yet, most of money flows into it, due to its network effect and brand recognition. It has all the properties of gold, that you also described. It was created in the image of gold.

You could create something similar no doubt. But would it get traction? Unlikely. These are for the most part winner takes all markets for a specific value proposition. For Bitcoin, it's digital gold. Ethereum is smart contracts, etc.

I'm not saying investing in crypto is a sure thing. It is very risky and speculative -- a bet on the future, with great upside if things work out. But at the current stage crypto is in (at least Bitcoin and Ethereum), in comparison to say a high risk investment in a startup or in a risky small cap stock, it seems (to me at least) to be a less riskier when looking at the potential upside.

If it doesn't end up being digital gold, it will most likely be worthless. But institutional money wouldn't be looking at buying in if they didn't think there was a decent chance of success.

Again, not investment advice, just a personal opinion.

Today the two major cryptocurrencies are bitcoin and ethereum. The two major cryptocurrencies two weeks ago were bitcoin and bitcoin cash. Three years ago they were bitcoin and ripple. Four years ago [1] the two major cryptocurrencies where bitcoin and litecoin. The next two major cryptocurrencies were peercoin and namecoin (they are 50-75% down over the last 4 years). Will bitcoin remain on top forever? Maybe. But it doesn’t have the properties that give some intrinsic value to gold. It’s not just the network effect. You cannot replicate gold, but you can create new cryptocurrencies (how many hundreds do exist already?) which are just as good as bitcoin or better. Why does the network effect matter anyway if it’s not used for transactions?

A high market cap (for wealth transfer bandwith and lower volatility), high hash-rate (for security) and large number of people willing to accept it as money (for conversion use) also give it value. Hence it isn't exactly true that you can just copy it, these other network effect metrics matter.
