Thanks for sharing. There are currently many ETH forks out there with unique features in the crypto/Blockchain space. For instance, Ubiq has a greater block time than ETH in order to reduce the number of orphaned blocks (uncles) on the Blockchain. It makes the network more stable than the original Blockchain platform. The only thing is that UBQ is not as widely adopted as bigger forks like ETC and EXP. At least, the idea/concept is there. We can have as many ETH forks as we like, but ultimately one will win. Considering that ETC is the biggest ETH fork in the blockchain space, it has all the odds of surviving for a very long time. I'm placing my bets on ETC, hoping that it'll become extremely valuable in the future due to its limited supply of only 210 million ETC.
Well, the Ethereum blockchain is currently clogged with high transaction load. The dev team is taking a long time to scale the blockchain with the adoption of PoS. Everything is starting to look like Bitcoin right now. In ETH, there are already Layer-Two solutions on the works to reduce the burden on the main Blockchain network. But we definitely need ETH to go full-fledged PoS in order to drastically boost transaction performance. Right now, ETH forks may be cheaper and less widely adopted than Ethereum, but they're faster and much more scalable.
My favorite ETH fork so far is ETC due to its hard cap in supply which resembles Bitcoin in every way. I believe that once ETH goes full PoS, miners will migrate into the ETC chain. As a result, ETH will become less secure while ETC will gain all the benefits. Since I still have some ETC from the fork back in 2016, I have nothing to lose if it turns out to become a failure in the future (I hope not). The more it rises in price, the better it'll be for my pocket. I think that buying and "hodling" both ETH and ETC will turn out to be a great investment in the long term.
