How is the limit calculated? Total fiat transaction amount? Or Bitcoin loading amount? Or is it card loading only?
This limit is for card loading only. More info about E-coin debit card limits and fees you will find here: https://www.e-coin.io/bitcoin-debit-card-fees-and-limits.
Thanks. Card loading is done through BTC. If I were to load 1 BTC into the card and the exchange rate then was 1 BTC to $550, that means my limit is left with $1950? [2500 - 550]
Yes, you are right. The limit is based on the fiat you have loaded.
