If you needed money for infrastructure for more arb bot, would you look for random novices and offer them 15% (and raise $3m in VC to market to random novices)? Or would you take out an unsecured personal loan from a bank at a lower rate, or a much lower cost loan from a counterparty involved crypto, especially one who understands the nature your trades?
