Cryptocurrency trading firm Cryptopia has faced a barrage of complaints after suspending some of its trading activity due to overload.
On Sunday the Christchurch-based firm suspended trading in two of its base markets, the Doge and Litecoin currencies, saying it could not handle the number of trades occurring.
Co-founder Rob Dawson blamed the high number of registrations and scaling issues for the trading halt.
"By the 1st of December we hit 500,000 users. On the 31st of December we hit 1,000,000 users. By the 3rd of January we hit 1,100,000 users. By the 4th of January, even with registrations disabled for three hours, we hit 1,200,000 users," Dawson said.
"With registrations paused again we're now sitting at 1,400,000 users. We've gone from just 2 people to over 50 people including contractors and consultants and we're looking to at the very least double that as soon as we can, but that also brings with it its own set of hurdles."
