Cautious as its a newbie who is selling and also its trading above 2$ so the question always arises why will he sell for 1 $ . So mostly it might be a stolen coins possible else any rationale person even if require money would sell for 1.8$ or so . Finally upto others to take their call.
I think there is no question here !! Some newbie with 1 post want to sell a currency with less than half of its real price . This does not need any question asked . He is 100% scammer , or mental idiot . And in both case you will be wrong doing business with him !!!
