is that bitcoin from silk road who got stolen ? well , if u dont know , they still have another 41,5k btc left ready to sell.

Are they needing some funds now and that's why it took that long for them to decide to liquidate it and the rest for four another rounds?
I guess that they're on the right time and the last remaining batch could be sold when the bull run has come. But if they intended to sell that in the first place, they should have decided to sell it on 2021.
not mean to judge, but they seems have enough funds , instead they seems playing with market i guess, lets say i am crazy and they have idea to take some of supply of btc by forcing sell in the low price.
