Accounts with Gold membership: Velocity caps at 120 and Loyalty Tokens cap at 5760.
Accounts with Silver membership: Velocity caps at 60 and Loyalty Tokens cap at 2880. Please note that for Silver accounts which have downgraded from Gold Membership, Velocity will be reduced to meet the Silver-level cap. Any Tokens which exceed the Silver-level cap will not be lost, although you may not gain more until you have dropped below the Loyalty Token cap for Silver membership.
Accounts with Free membership: Velocity caps at 30 and Loyalty Tokens cap at 1440.
