in the past, i would say it's the same. but csr can now redeem at up to 2cpp on chase travel but csp only up to 1.75cpp, i have no experience with miles brokers, but this could be a viable option for the brokers; less risk, more availability and while they may earn less per transaction, they could complete more transactions quickly, resulting is overall more payout. so csr points are technically more valuable even when selling to broker, but whether they will pay more for it is another matter
