Good day sir, generally everything could be stable depending on the type of traffic and dispute management. We’ve had some good success stories with HK and Singapore setups since they’re quite unique jurisdictions and more complex to open corp with. At the same time, we also have clients running other jurisdiction setups that we offer over long-term (1 year+).
For high volumes, we usually recommend setting up multiple merchant accounts through a payment orchestrator we partnered with, setting limits, and diversifying risks - it’s generally a good practice. Usually, once accounts surpass the initial 100–300 transactions, they tend to become more stable.
I sent you a DM - if you have an inquiry, please let me know. I’d be happy to discuss your case so I can suggest the most relevant option. Thanks!
