How long it takes to cash out on CSGO sites depends on a series of factors. The whole process can be influenced by the website you choose, whether the skin is listed instantly on the platform, and whether there is enough demand for it. So, while some people are luckier and spend less time doing a CSGO cash out, others may end up spending more time.
Generally speaking, it may take between a few hours and several days to perform the cash-out. This is why you should carefully research the platform you choose before doing a cash-out on it.
