According to Bloomberg, BitMEX co-founder Arthur Hayes has returned to the investment field after receiving a presidential pardon from Donald Trump. In addition to continuing his involvement in crypto projects, he has also invested in a stem cell therapy company with clinics in Mexico and Bangkok, and joined its board this summer. His family office Maelstrom has invested in three digital asset vault companies (DATs), but his partners warn that this trend could spiral out of control or pose risks to the broader recovery of the crypto market.
