A possibility is by Allen exiting and selling the 100 shares of preferred stock to David Garrity, he is trying to protect the shell. From what I have read from filings, his attempt at merging $GBV with $MARA has not been working out too well.
Another reason could be that he has to exit to avoid any possible conflict-of-interest with his other venture at this point-in-time.
Bottom line, a great hand-over to the right person, David Garrity, to be custodian of the $BTCS shell.
Interesting times ahead, maybe time to get back in?
All stated IMHO
GLTA!!!
