Giant bitcoin exchange Mt. Gox has delayed plans to support the litecoin cryptocurrency, following another DDoS attack last month.

The Tokyo-based bitcoin exchange had previously announced plans to support the bitcoin alternative. However, it postponed the move after the most recent attack, which happened on the evening of April 21.

Nevertheless, the company announced it still plans to support litecoin "soon".

"We were planning on doing so two weeks ago, but events derailed that plan," said a statement from Mt. Gox. "Right now we are focused on overall stability of the exchange, and will launch LTC (litecoin) when we are ready. Otherwise we could be further complicating things."

Litecoin trades on BTC-e, where it was worth just slightly more than $4 (US) at press time.
