Did anyone track their money and find ICO bitcoin address? Can anyone confirm that over 1000 btc was invested? I've been offline for the last two weeks and as far as I understand Lisk team doesn't give any proof. Or am I wrong?
This was the biggest unseen flaw prior to beginning the ICO. The coinbase multi-sig vault account they use for keeping the ICO Bitcoins safe does not provide them with a BTC address.
What max has done to remedy this problem is he's posted several screenshots and videos of the coinbase account associated with the ICO.
You're not wrong, they are very aware of this issue.
Found it!
A video which demonstrates our coinbase vault....in the coinbase app and website. The quality is very bad, because I had to record it from my Android Phone and edit it using some Android App. Else it would have taken me many more hours to upload the video to Google Drive from the smartphone. It should suffice for now.

I already wrote the coinbase support to check out if there are other options for us. They forwarded my case to a "subject matter expert".
After examining the issue I forwarded your case to our subject matter experts who can help. They will get back to you shortly. Thank you for your patience while they take a look. Please feel free to reach out if you have any further questions.
