Peopel ar panic including me because of uncertainty in crypto world some coins which never thought turn out to be scam like Centra , POS token made me think twice to invest . Yes as you said if fear gives nothing positive whats the need of panic . As the reverse with immense courage if you put money then loose everything there is no point of getting huge courage. Calculative risk always better. Finally dont invest what you cannot afford to loose.
For me, to be honest.. There is nothing to be afraid of because if you are afraid of scams you must avoid it. Before going in to this crypto world. You must have a proper knowledge for you to know about coins, tokens, campaigns and projects. And if you have been scammed then take it as a life lesson. You should be careful next time. And one more thing, if you want to gain money then you need to trust and waiting is a must.
