The daily transaction limits depend on the regions you are in.
The specific details of the per transaction limits can be found on this website.
We currently cannot increase these limits for a specific customer.
The daily limit is calculated not as a calendar day, from 00:00 till 23:59, but as a 24-hour period since purchasing.
The monthly limit is counted as a 31-day period since the purchase that reached the limit, and not as a calendar month.
