Could you explain please, when lending BTT on just... @officialjustlend

When lending BTT on JustLend, jToken (JST) is the receipt that must not be sent to a third party. jToken is a tokenized representation of the BTT that is held in your JustLend wallet. It is generated when you lend BTT and is used to track the amount of BTT that is held in your wallet. The jToken is a unique identifier that is used to keep track of the BTT that you have lent, and it is also used to ensure that the BTT is returned to you when the lending period ends. TRX, on the other hand, is the cryptocurrency used to pay for the BTT that is lent on JustLend. Therefore, TRX should not be sent to a third party, but the jToken should remain in your JustLend wallet.
