In the financial and crypto space, choosing the right account type is really important because the ad restriction rate is higher than usual. In my personal experience, stable accounts are usually those with a clear operating history, clean domain names, and are properly set up from the beginning.
Regarding choosing an agency, I think you should prioritize agencies with transparent processes, ready to support when the account has problems, and if possible, do a small test first. You should not rely solely on price to choose because long-term stability is a key factor when operating in sensitive industries.
Hope you find a suitable solution soon.
