It was started as a joke but then “ironically” took off and became a thing. The Founders of Dogecoin point to their own product as an example of the problems with ICOs.

Dogecoin is total BS, and even the people who founded it admit as much.

here's some, do you know of more ?

What's the expected price of Dogecoin in 2018?

After the DAO hack, There were two solutions:

-Blacklist the attacker from all transactions on Ethereum, so the attacker cannot cash out. The stolen Ether would basically be locked away forever.

-Reverse all the transactions related to the DAO entirely. The investors get their money back.

Which fork to take?

Option one was called a soft-fork because it was a relatively less drastic measure within the confines of the system design of Ethereum blockchain. This was implemented while the community was attempted to arrive at a consensus. Unfortunately, at the eve of the rollout, a vulnerability was discovered and the soft-fork was abandoned.

Option two was a hard-fork because it was an unprecedented proposal: split the Blockchain itself. This was and still is controversial not only because because Ethereum would be split, but Ethereum is a decentralized system governed by “code law” and this amounted to an intervention by the “1%-ers” of Ethereum in collaboration with Stiftung Ethereum (Ethereum Foundation), this arising a de facto central authority. It was a shakeup of fundamentals at the core of the “religion” of public blockchain and cryptotokens itself. It's as if the Pope converted to Islam and recommended all Catholics to also convert.

In the end, the Ethereum community voted in favour of the hard-fork. When it was implemented, the investors got their money back and that blockchain is now called Ethereum (its token is ETH). The other blockchain with the DAO transactions left alone became known as Ethereum Classic (its token is ETC).

ETH is the ‘authorised’ or main Ethereum ‘fuel’ or Cryptocurrency, which has had the update applied with the ‘hard fork’ for security reasons.

ETC is the ‘unauthorised’ or secondary Ethereum ‘fuel’ or Cryptocurrency, which maintains the original Ethereum model.

Why don't these startups fork this or that blockchain ?
