In wake of Bitcoin spike, Instawallet halts service and Mt. Gox "eats" DDOS
Two days after Bitcoin blasted through its all-time price—shooting past $100 per BTC—Instawallet, one of the digital currency’s easiest-to-use wallet sites, has shut down indefinitely. Bitcoin’s price peaked at around $140 late Tuesday but has since fallen back down. It’s hovering around $128 at present.
