I am new on here but invested into DUECOIN in the pre-sale around Sept 2017 last year through Coincrest. Interesting that both people who used to work there Stan and Dave Bennett are no longer there anymore and impossible to get any answers. If you contact Coin Crest as I have done they will tell you its nothing to do with them even though they promoted it and gave their clients the opportunity to invest into it. Without that I would never have known about it. Also, interesting is the fact of how hard it is to keep people up to date through their twitter feed and FB. If you read through on the responses there on twitter you will find other people who have reached out to DueCoin for answers with no reply. Are they really too busy to keep the community posted? Was the whole lottery thing they did just a rouse to keep us distracted. It is hard not to think it is a scam at this point since it will be almost a year soon and if Due C wants to prove us all wrong then go ahead. I will be happy to be wrong. If you look back at their twitter feed you will see its been a while now. I am losing faith. I have emailed them, tweeted and posted on their FB page. Nothing.
I am in the same boat as you. As least you got a response from Coincrest. They just ignored me completely. I had also tried to contact DUEC via FB and Twitter with no response. I've lost faith in them long ago.
