Cryptocurrency uses the blockchain as a fundamental building block. For good faith proponents of cryptocurrencies, the appeal is that they provide the potential to do low friction digital payments (e.g. "micropayments"), reduce the barrier to entry to participate in financial transactions and allow for a single, global unifying currency.
You may disagree that Bitcoin, or any other cryptocurrency, has the potential to do this or whether it can actually do this, but that's the appeal.
Proof of Work (PoW) is probably necessary for a decentralized currency [0]. Proof of Stake (PoS) can be a valid cryptocurrency but fails in it's centralization criteria [1].
The Lightning network provides a layer-2 solution to payments, increasing transaction throughput and, thus, reducing PoW energy usage [2]. This might get into centralization territory but maybe this is a happy compromise between energy usage, throughput and centralization. In some sense, we have many "layer-2" like structures on the internet, with DNS caching, replication and load balancing etc.
> Most importantly, non regulation doesn't always mean good. Otherwise why we need law and government? Why not live in the wild west and let strong people kill weak people? Why not let big company play the monopoly?
As a counterpoint, regulation isn't always a good thing when it's been captured by hedge funds, oil companies, pharmaceutical companies or other special interests.
I'm having a hard time understanding if the line "Why not let big company play the monopoly?" was meant to be rhetorical in the affirmative or the negative. Are you suggesting that company monopolies are a good thing? Or are you suggesting that a decentralized currency unseating what is essentially the current banking monopoly is a bad thing?

I have to say that I don't know any blockchain P2P-networks that have succesfully done this (Sia/Skynet maybe). I don't advocate for 'token for every app' or ICOs, which end up being ponzi schemes. Currently I'm more interested in what's being built on Bitcoin and Lightning Network, such as https://www.impervious.ai and the ecosystem on https://getumbrel.com
