Hi DanielLucasAguas, welcome to the Morpher Community!
This quote from the Morpher Guide might answer your question:
Morpher Tokens power our unique trading platform. They're used as the settlement currency for all investments. All trades on Morpher are settled in Morpher Tokens instead of USD or Bitcoin. Morpher’s currency is staked via its smart contracts on any asset supported by our platform. As the underlying asset gains market value, the smart contract mints new coins to the investor, and if the underlying decreases in value, the staked coins are destroyed proportionally.
So if your balance says 4500, this means 4500 MPH (Morpher Tokens).
A trading example can be found in the 9 Frequently Asked Questions About Trading discussion.
