Bitcoin’s price swings on Wednesday were caused by an influx of new buyers and software, Mt. Gox says. The Tokyo-based exchange saw its price hit US$266 at one point, then fall to $105 with high lag times for trades. Mt.Gox has spent an “enormous” amount of money on new servers for its bitcoin trading engine. BitFloor, the largest U.S. bitcoin exchange in New York, warned of delays and technical issues with its website.”]
