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