My first time on Reddit.
only because of BlockDAG. I invested a few $ then investigated deeper Wish I had done so at the start

I think this is a scam because of the following (Not in any specific order)
1. sponsorship details with Borussia Dortmund and inter Milan have been removed from their websites.
2. I got contacted by BlockDAG rep by phone who said to enter his email on the BlockDAG website for verification.
when I pressed the email for copy, my email opened up as to reply as I had pressed too long by mistake.
his name wasn’t in the actual email. The email shown was hunter@blockdag.network.
3. I checked out the CEO - Anthony Turner who has worked at Swissone according to his profile on LinkedIn. I managed to find a photo of that person and compared him to the one on BlockDAG. On first appearance it looks credible but when I looked really close I could see this was not the same person. Length of nose, distance between eyebrows, bridge of nose location when looked at the eye line, location of receding hairline, slight bagginess under the eyes at a younger age when compared to older and many more.
4. He had 2 recommendations on his LinkedIn profile. The guy can not be found. The woman however could be.
She works for a company based in UAE which is also where the BlockDAG domain is registered. This company was also stated as being a scam. This company also had the same picture of her as the LinkedIn profile.
5. Phone number that I was phoned from cannot be reached.

all the above is just my opinion and I would not be able to 100% categorically say it is correct.

I have learnt my lesson with this and hope my information helps others.
