When Silvia Tabusca, a Romanian organised crime expert from the European Center for Legal Education and Research, began looking into iEarn Bot, she discovered that many people in other countries had also lost their money in the scheme.
What surprised her most was the scale of the operation.
"From what we have seen, the number of investors is quite high," she says. "In Indonesia, for example, they [iEarn Bot] claim they had 800,000 customers."
"At first the app works very well," says Ms Tabusca.
"When they have enough investors and enough money invested in a specific country, they don't allow that country to withdraw any more - and they open other countries."
