I think if darkcoin gets more well known regulaters might bann it
Have they really banned any coin so far? No they haven't. Also you can't really ban a specific coin, especially since it is trading mostly BTC/DRK.
They can target exchanges to delete the coin for example, that could be a start. So i would say don't get too greedy while you are in profit.
They can't depending on the country. Besides, any exchange removing DRK now would lose a lot of revenue. The volume in the past 24 hours is almost 4 million USD.
Closure or loss of some earnings...hmmmm. No big exchanges will risk it if they try and ban it. It won't have this much volume after the pump is done.
Don't be such an obvious pumper, at least pretend to consider some possible negatives. The fact you believe there was no instamine is the best part.
