Indeed that was good year to discover and come closer to new projects which might not be possible if there was bullish market. For example QuarkChain I came to know about it in last quarter and once I studied and understood it jumped on it. That was best deal at prices I bought and feel same excited for this year for the cool stuff is planned.

Do we have any pool to mine on sha256 for now?

That is link to smart contract you can verify the status of this token it's ERC20. At the moment it is using ETH blockchain so it is possible mining of this token.

Yes, i just want to ask something about the POS model whether we are going to get any coin for holding Quarkchain because i heard some people kept saying me about this POS model?

Hope guyz you have noticed that the signatures for "profile" have arrived, stakes have 2x!
Go Quarkchain!

Current circulating supply represents the amount they raised from public. If you look at the protocol there will be some kind of mix-up of pow/pos and remaining tokens will be used for staking/mining. That is maximum supply ever and will be there in years. I also started to follow the project late and still trying to polish my knowledge and information about it, even I have picked up tokens already.

Yeah Quarkchain team doing best to spread the word QKC, allocation reward is not very big but hope so after mainnet price will skyrocket.
Right now i joined twitter campaign and daily i get enough stakes, let's hope hunters will get enough reward for their work.
I think this campaign will be end on 15th February and they will launch mainnet next month, i believe! 

Yes, already they mentioned the dates when the bounty campaign is going to end, but with the popularity, they are getting will get more awareness about the Quarkchain project. The team behind the project are doing very good in the market with active updates and developments they do.
