So basically, it is a much advantage to the people that resides on New Zealand right? We all know the volatility of cryptocurrency especially Bitcoin, and recently it's transaction fees is increasing as well. And supporting only one crypto would I guess have you less clients than what you are expecting. I do suggest XRP, ETH, LTC, and DOGE to be another crypto that supported by your platform. With those altcoins low transaction fees and fast system, you would likely to have a better set of clients/users especially gamblers that also prefer the use of those.
