To your question:
Well there are a lot of devs and employees never got paid. They had to move the office also very quickly suddenly. Probably they didn't pay the first office and now the whole "company" contains of 2 china employees keeping the hot air system alive by sustaining a telegram/discord chat with few fake accounts.
I mean thats super cheap.
Raise 53 Million (if ever), hire people, rent an office. Never pay anything, go travelling and never come back to the country you could be sentenced for not paying staff and rooms. I mean its Serbia. What this country offers to you if you have so much money except a mafia system trying to steal it away from you. People with that much money leave it anyway. So a total win win situation for the twins. Taking all the money away from investors who are later not able to pay a lawyer because they have now their money. And just disappear from the window.
Easy even with only 2 Million USD. Meanwhile people suffer under strong mental problems like someone in a straightjacket shouting "price will go up you fcking trolls. Long life the sholoms"
So many people believe this was a scam from the beginning but just to throw people off the scent they hired "staff" and rented an office or two. All the major doubts about this scam were confounded the moment Jack gave his explanation on the infamous Reddit post.
The irony for Jack of course was that for such a long time he was himself propagating the "pro-MobileGO" message, advising investors to hold tight and was bashing the voices that were trying to sound the alert. In the end it seems Jack himself got well and truly betrayed by the very same "owners" of this "project" that he was once upon a time defending.
Jack claims he was working unpaid for a year so he lost out on money, salary and his reputation. All those investors lost out on their investment. It seems everybody lost out but until or unless the "owners" show proof of where the ICO funds were spent people will think just the "owners" did not lose anything because they siphoned the funds off for themselves to fund their lavish lifestyle.
