They still have ample of time to get ready especially this time when crypto are lying low and people are not that interested yet.
Current market isn't lying low, but just busting out normal volumes that are still enough to exceed the $10 billion daily volume mark. Hype volumes and demand don't represent the reality, and should be discarded.
The crypto market looks very healthy as it is right now, and even in current times exchanges badly struggle to get things right, or to open up their registrations again. Their backlog is only growing larger, and that won't stop.
The only thing they can hope for is that there won't be another insane burst of speculative hype usage further putting them into backlog debt. We'll see how they fare next year, but I don't have high hopes.
