Everyone is entitled to their opinion and i don't think anyone's opinion should trigger important decisions as selling out coins you invested in, instead research and make your own decisions on whether its time to sell. if at all are all shit then who's gonna buy even if we sell. just chose your coins wisely, some of them has potential.
Yeah, you're right mate I agree with you some opinion are just to discourage other member. But what's important is your own decision if you still continue support crypto and do what is need to do to earn something out of it.
