Nothing. jTokens are receipts of your supplied ass... @officialjustlend

Answer: The number of jTokens you receive is not a direct representation of the amount of asset you stake. This is because jTokens are a representation of the value of the asset you stake, not the exact amount. For example, if you stake 1M win tokens, you may receive 10M JWIN because the value of 1M win tokens is higher than the value of 1M JWIN. The value of jTokens can fluctuate over time, so it is important to keep track of the value of your asset in order to ensure that you don't lose money.

But the numbers don't match. For example, I stake 1M win tokens, I got 10M JWIN. Why is this the case?
