An open ended question !! And also a very good one.
The answer depends on what you hope to derive from 'mining' a coin.
If your objective is to mine this coin because you feel it has quality code and features , is well maintained by experienced developers and is also not just a copy/paste of something else I would say absolutly it is.
If you believe it is going to be a long term player in the alt coin world and want to stock up now it would be also.
If you are only looking for something to mine to 'exchange' into bitcoin or mine to earn 'money' then the answer depends on what mining hardware you have available to you and how much money you are willing to spend on electricity and other resources to possibly mine at a loss for hope of future financial gain.
The worth (or value) of anything means different things to different people.
Some say something is only worth what price an arms length transaction will fetch you if you sold the item in question.
Others place 'worth' above this and may have personal or sentimental reasons that something is 'worth' something to them but may be considered of no worth to others.
So:
How do you define worth of a cryptocurrency ?
For a majority of the visitors of this forum the answer to that question is what the current 'exchange' rate of the cryptocurrency is to traditional currencies like the dollar, yen, pound, eruo ect......
I do not mine this coin often since I lack the best mining gear for it but I do mine it.
I do not classify myself in what I describe as my opinion of the 'majority' of visitors to this forum.
Is this coin still worth mining?
