All below addresses were emptied this year. Most of them in Sept. 2019. Around 2982 BTC in 21 addresses. All addresses were first used in 2011, and dormant until now. BCH is still there except 1 address.
No spending transactions on them so the public key was not known. The owner he suddenly remembered after 8 years that he had some BTC?
What are your opinions?
Most likely an insider into bitcoin market manipulation and he was given a heads up about the impending price collapse due to tether fractional reserve shenanigans coming to light from the New York Lawsuit.
