Upcoming with Merger with BTCS, page-32

BGL are merging with BTCS not simply investing in them like with DCC. The merger will mean that the shell corporation that is BTCS, will heavily benifit from BGLs assets, and BGL will benifit by having control over the publicly listed company.
BGL
BGL aren'T a public company so have no obligation for continuous disclosure, but they seem to be everywhere so they've got deep pockets. To give you some idea of BGLs position, their holding of DCC shares alone will be close to $40M and they where a market leader operating a very profitable business even before the DCC investment. I would probably go as far to say BGL are one of the blockchain investment firms out there, they've got deep connections with major blockchains such as: NEM (through their recent corporate partnership), bitcoin, (they operate a huge bitcoin mine) and ethereum (through DCC, they are heavily affiliated with ADCA which is a member of the ethereum alliance).

BTCS
I see you are worried about their debt, and the 4M liabilities does seem concerning, but here is why I wouldn't worry about it. BGL already transferred them enough money to settle all their outstanding debt. If you simply look at the simplified presentations of their recent quarterly report they list $4M of liabilities, however, these are mostly derivative liabilities from outstanding warrants and capital notes, i.e bonds payable in the form of dilutive equity issuance following the exercise of warrants (at least that's what I gathered from the report, it wasn't very clear) . I can't imagine that would concern BGL all that much, given the amount of outstanding options DCC had and the minimal effect that has had on the stock price. Who knows what BTCS will do next, all I know is that DCC had a massive shift to a very profitable business model after the BGL investment, its possible we could see the same with BTCS. BGL have proven they know how to capitalize in a market that is mostly research and development at this stage, so I trust they know what are doing.
