Woo is an early adopter buying bitcoin since 2013. He has likely been
buybuying and selling his bitcoin bit by bit along the way
to lock in
thesome very big profits. He has been holding for a long time so it is not surprising to hear most of it has been sold by now.
It is
verypretty rare for most people to hold for such a long time without selling anything, especially during the earlier days and cycles
of bitcoin when the volatility was so extreme. That is not an easy thing to do.
