Ill name some names dammit. ETH. And any other coin with an independent block chain (none of these ERC20 tokens). the reason? there is no way in hell smart contracts are going to work as a layer on the Bitcoin block chain, given the level of congestion going on now with this low level of adoption. people are digging the trust less nature of these things, even though the trust of the entire scheme is only as good as the contract is coded. I digress. the coins designed to facilitate this will be the most valuable, esp the ones that are proposed as business solutions rather than end user products.
I semi like the concept of ETH with ETH being the network for distributing contracts (mini type of programs) and then charging "Gas" for hosting these programs
so that I could run a dirty as you like porn site (Joking) and no one could ever take it down but after looking at some of the code for these contracts it becomes
obvious that the scripting language (Java-script almost) is little more than a bean counter that runs on the network and allows you to store bean values in the block-chain so long as you keep paying "Gas" that must be paid for in ETH
Earning a bit of "Gas" by providing services to other ETH contracts that would allow them to validate credit card numbers via your service is not what
it is about (sad to say) because you are stuck with just talking within a closed system and cannot kick out using HTTP request and sockets to pull data
from the real world.
Fantastic for converting Red-Beans to Blue-Beans, having a balance and calling it money needed for a new ICO
and then having public history for the event held within and mixed up with the ETH block chain but not much
good for anything else from what I could understand.
I was kind of hoping for something like Tor's onion sites that would be fast and not going down if I un-plugged my
pc at home that hosts the site/service and would work without having to be accessed via Tor from the tinternet that
was Pay-as-you-Go for the service using ETH and GAS being charged based on the resources used by the site/program
Having said all that I think ETH has more to offer in it's own way than BTC were fork/clones might become ten a penny
