The scam is to create a new altcoin, give most of the altcoin supply to the founders, then try to force as many people as possible to use the altcoin by deploying it as part of something popular like Signal.
Now if anyone wants to use Signal’s money transfer feature, they have to buy MOB. The CEO of MobileCoin was in the threads yesterday pushing the website where they were selling MOB.
They don’t really care about transferring money. They just want to sell MobileCoin and pump up the price by making it look useful.
