I have seen this in the past. This shows up when they are making updates to the site so they need to temporarily turn it off. It's reasonable to be afraid about exit scam everytime you see this on a crypto website but it's simply too early to risk about any exit scams, just wait and it will be back up. This coin will eventually pump so it's good to baghold some.
Don't be worried, the site is already back to normal and working for me again. Not every coin pulls of an exit scam, there are still trusthworthy people on this planet, luckily.
OP, don't rely on a single online service, it is better to spread your risk, to reduce the loss if one of the services that you are using disappears with your funds.
