Own
- Steem -- Steemit is growing 5% week-over-week in users and posts
- bitcoin -- has survived more in-fighting and politics than any platform
- neo -- asia ethereum token platform with low energy consensus approach (dBFT)
- bitshares -- a bit speculative, though has a live product - a decentralized exchange
- gridcoin -- replaces PoW with PoS + payouts for contributing to scientific computing
Intrigued by:
- Cardano - appears to have interesting PoS features, good dev team, interesting roadmap, though I've hear their PoS isn't particularly novel or awesome from @dan
- Nano - alt platform that purports to have superior scaling
- Xtrabytes - alt platform that purports to have superior scaling
- EOS - concerned that token doesnt seem to do anything, but platform seems interesting
- Ripple - interesting platform and path to market, also concerned that coin won't be used
How about Raiblocks?
Raiblock has rebranded to Nano, so yep, also of interest.
Similar to Cardano/Xtrabytes seems interesting, claims awesome scaling. I'll be following but I want to see how they progress. Also, a bunch was just stolen and I want to see them handle it responsibly (aka no hard fork).
