I agree with the statement made above by HelloWorld.
These scammers are using the Same strategy they’re using for the block trades – There’s no real discount code at all. Everything is being manipulated on their fake dma screen. So all those profits you’ve supposedly made after each trade don’t actually exist. That’s why they encourage you to invest more cash into the block trades in order to supposedly gain bigger profits, they’ve been using psychology all along to get participants to transfer more cash into their station1 account, and to withdraw as little as possible, for fear of missing out on the huge profits.
And for those engaged in the IPO, I don’t know if they will ever get a chance to withdraw any of their cash, as I reckon, as soon as one IPO is completed the scammers will assign another set of IPO shares to continually lock up the participants’ cash until they finally shut down the whatsapp trading group.
