Is there any evidence that Dean is in fact trying to make investors whole by buying the old BKB tokens?
I haven't seen it.
If someone had sold at a low price, their claim would have transferred to whoever purchased their tokens.
Lol, that would be Dean! He told people that BKB tokens would expire, and should be exchanged for the BKT tokens he created. Not having them expire (and possibly buying them back from himself) is just shady.
