Tax lawyer, approaching two decades in SE Asia. I started in Thailand in 2003 and came back for good in 2105. Worked for development banks as a consultant for a while, but got into crypto relatively early...I asked around and realized no other lawyers---especially other tax lawyers---had a clue.
I began to specialize, and that was that.
We still do tax returns in the season for NOTH US and Thai SIMULTANEOUSLY, which saves a lot!
I'm a huge reader, physically banged up from sports when young; just started TRX, boxing, tredmill.
