For me it was when his English and grammar started to fall apart in his updates. He started hyphenating words like "Bitcoin-mining".

On top of it all though, it was his inability to prove that he has done anything other than a few scribbles on a million dollar cheque. Meanwhile, he personally benefits financially even though the core business is now worthless. He didn't even try to make it work, because that salary is all he wanted out of it. Proof of this is that he didn't even bother hiring someone useful, only his family who had probably never heard of "bitcoin" until getting hired to fold cardboard boxes and sort through sales orders. This man is literally trying to build a rocket ship out of marshmallows and school glue. He doesn't have a single clue of how to make us successful, only himself by stealing our money for his own families wealth. That, my friends, defines
SCAM. I see where you are coming from, VE. I agree about the grammar, that is a red flag in my eyes as well. While excusable, I never assume it is excusable because it is also scammy. Saying that he formed the company just to reap the benefits of the salary for him and his family members is a large claim...I'm not saying it's impossible but it doesn't seem like a good way to scam people and get away with it. I suppose he could argue that he tried his hardest but failed and scam us etc, etc... but in court that wouldn't hold up because they would judge the backgrounds of the family members involved. If the company failed and there was a lawsuit due to scamming concerns, the courts aren't just going to say "hey you invested in this company and it failed, tough shit", they will look at the motives behind Ken and family and investigate.
Don't flame me, VE, but I honestly think you have taken things a little too far in your head. I'm not trying to tell you that you are wrong! I have no crystal ball, obviously. HOWEVER, it is quite obvious that everyone is paranoid, that is for sure...and obviously scepticism and paranoia is good in moderate amounts but this is utter madness. ACTM does need to come out and clear up a lot of information so we can stop arguing over nonsense. I'd like to see proper accounting documents as well.
