I think we should get used to this scenario, because since the Internet has become popular and online payment systems have grown in importance, hackers have always been a step ahead of any system of protection and security, so I do not think there is more attacks and vulnerability that before, but now we worry much more than before because we are more and more who are involved in the issue of online finance.
I agree on you.Scammers have already been here while the price is still low and now that its gaining a high price,the rate of scammers too have been increased making steal all of those hard earned money of the people.We cannot do nothing about this but to be more careful and cautious in every actions we make not to lured by scammers out there.
