If it is a Bitcoin transaction, it must first be confirmed by the network. This process, which does not depend on us, can take from a few minutes to a few hours (sometimes even more).

Moreover, for security reasons, all transactions are validated manually, which can take up to 24 hours.

Upon confirmation of receipt, the funds will be split and then automatically and sequentially placed in arbitrage pools.
This takes from 6 to 24 hours maximum.
From that point on, they will begin to generate interests. So you don't have to do anything else.
