The profitability of the 5 largest Tezos delegation services

Delegation services play an integral role for Proof-of-Stake blockchains that grant the delegation of tokens in their protocols. These services allow participants who lack either the required number of tokens or the technical skills to be a validator, enabling them to participate in the network and gain rewards. 

Traditionally, these delegation services will take a percentage of the rewards for their work, which normally varies anywhere from 10% to 30%. Companies have even formed to cater to these delegation services.
