APR is simple, APY includes compounding
APR is the base annual rate before compounding. APY is the annualized result after rewards are reinvested or compounded according to the product rules.
Two products can show similar numbers but produce different outcomes if one compounds daily and another pays at maturity.
Read the reward schedule
Check whether rewards accrue daily, weekly, monthly, at redemption, or at maturity. Also check whether the advertised rate is fixed, variable, estimated, or promotional.
BitHunt labels APR/APY where sources provide enough information, but users should still confirm the terms on the exchange before depositing.
