- Alts work like a testnet for bitcoins (looking forward seeing Litecoin with SegWit)
- Once an alt feature looks working it might get adopted no matter onchain or in a side chain. (RSK)
- Alts mostly need bitcoin to trade and some bitcoins might be always reserved / locked for this.
- Alts might help to generate a closed bitcoin economy
My favorit comes here:
- Alts work like an infinite fear generator (Hydra) against any try of regulators to bring bitcoin down, since there are too many to kill and its very easy to just create a new one (like a Hydra cannot be killed by chopping off some heads, even the biggest one!) > crypto world is anti fragile and it will stay on this solar system from year 2009 on.
Any other things missing here?
Those are all correct. I am mostly looking forward to Segwit as well. It is great that we can use altcoins to test different ideas before making changes to Bitcoin. One thing that you could have added is that altcoins create competition for Bitcoin. They also show people that are thinking about investing in Bitcoin, that it is the best cryptocurrency. There are no altcoins that are even close to the price of Bitcoin.
Wow! now those are some solid points and people who are against alt coins should read and try to understand. There are many trolls in here who hate alt coins and keep shouting their support for bitcoin only. Alt coins are important for the development and for better adoption of bitcoin. They both complement each other and the best part that I like is Alts give you an opportunity to make more bitcoins by trading/investing!
