Well, i believe by now, you must have gotten your answer, so yeah, there are actually several ways one could earn passive income from crypto, and one of those is by staking, there are two types or forms of staking, and that is the centralized form and the decentralized form...
But you will be able to get a good profit only if you have placed a large amount on the staking. And although OP does not write about the size of his deposit, I can assume that this amount is very small and, accordingly, he will receive a small profit, which will not be able to somehow increase the existing deposit.
