My girlfriend has her own business & a lot of her supplies are made in China, it's the Dragon Boat Festival this weekend so literally all of China grinds to a halt this weekend. The factories that supply my partner emailed her to let her know there may be a delay with her deliveries. Any way I just thought I'd mention this here, might be a reason why the BTC price has dipped a bit if it's like holiday season in China, banks are closed etc.
