Short summary - this page is more like an index to provide a quick insight, read detais on referred pages and elsewhere

Our civilization grew up (well, still a baby, but "grew up" sounds better) from the art of written communications and the specialization of professions (the useful ones are mostly related to science and technical knowledge).

'''Clearing systems ("money" or "currencies" in everyday language) made specialization (and therefore our civilization) possible.

Small currencies (often in the form of coupons, vouchers, or clearing between a few parties) have been around since ages. Transactions can be initiated in several ways

How the transactional information is stored:

One might notice that [coinmarketcap] grows several percent each day (which means that people investing random gain more than if they could in any bank or share)

There are multiple ways to make transactions without the extreme environment pollution of sha256 hashing (bitcoin, ethereum) and the fragility of centralized title-server farm (stellar, ripple).

Ethereum classic ETC (not to be confused with electronic throttle control)

When it was first advertised to pay with ethereum (for VEMS ECU, recommending to buy some extra, which allows negative purchase price in the end after ether monetizes, which happened more spectalularly than envisioned), there was only 1 branch, called ether (which is now called Ether classic).

While bitcoin only allows keeping track of bitcoin balance (an extremely limited system), Ethereum allows keeping track of ether balance OR ANY information and processing via any (deployed contract) algorithm automatically, a truly generic and practical system.

ETC Ethereum classic is the chain as it was ment, adhering to the ethereum principles.

ETH Ethereum is a hijacked (hard-forked) chain (with a modified sourcecode in effect after certain blocknr, which violates the basic principles: "creating applications that CANNOT be shut down"

Since any smart contract can be executed on the ETC chain (except that ETC balances are affected, not ETH balances), and ETC chain transaction cost (gas price) is lower (in USD),

the ETH ( "official" lost it's purpose of executing smart contracts. (but note: the official ethereum ETH is more monetized at this time; basically it works as an improved bitcoin; there is some chance that it might gain another 2x and it could easily outgrow bitcoin market capitalization; hard to predict but likely).

Still, the stupid DAO story seems like a happy ending:
