# Secondary Market Trading

Since $EHO has a unique binding exchange relationship with the "ETH fund pool", the ETH in the exercise pool can be exchanged at any time, which is equivalent to a stable currency backed by ETH reserves, and will gradually expand the scale as the number of projects increases. Therefore, $EHO has strong liquidity, and transactions in the secondary market can be realized at any time and the difference can be earned.
