Bitfinex announced an improved fiat deposit system that will allow know-your-customer (KYC) compliant customers to initiate deposits in USD, GBP, JPY, and EUR on Tuesday. This comes after last week's news of Bitfinex halting fiat deposits and rumors of insolvency, which it vehemently denied in a blog post. “We believe this system to be significantly more durable in the face of sustained attacks by our competition and their supporters,” Bitfinex wrote.
