Personally I feel this is the biggest scam that has remained unraveled because when people wants to invest or rather trade they easily go into this top Alticoins with the belief that it is already at the top and nothing is going to happen to it. That’s why you see this projects brag about there ranking on their social media handles to sway people to the coin.
Another scam is believing nothing will happen to Alticoins because it is listed on many top exchanges. There area many projects that have also used this has bragging rights when they do adverts and this trick has also worked out for so many projects and the funny enough it is still working out for them because these are the things people use as case study when they do there research about a project.
