Tokens in the EOS ecosystem SPONSOR bepoornomore for a period of time by providing a quantity of tokens (For example, IQ, KARMA, HORUS, EOSDAC, RIDL, TRYBE, CET, OCT, BET, etc)

This allows members with POOR tokens to cash them out for the sponsored token. So you can stockpile poor tokens until there's a sponsor that you really like and trade them in for your preferred token, so long as they sponsor poor.
