Today on the Brief:

  • Square puts up monster Q1 bitcoin numbers
  • First crypto comments from new SEC Chair Gary Gensler
  • 3 new institutional bitcoin developments

Our main discussion:

As bitcoin becomes more mainstream, the attempts from the powers that be to control it will become more subtle. This week, NLW argues we got a preview of a new approach to trying to exert that control. He argues there is a new attempt to Balkanize Bitcoin and looks at:

  • Iran banning crypto that wasn’t mined in the country
  • Marathon mining an “OFAC-compliant” block
  • Kevin O’Leary insisting on only owning bitcoin not mined in China
