I expect some BTC businesses to be struck hard by this. Some may have had the bulk of their capital in MtGox, probably the smaller ones that dont check news too often or have an old account with them. But even big ones that distribute their holdings accross exchanges will loose 20-30% by this.Does anybody know which companies have substantial holdings at Gox?
Why would BTC businesses have a substantial holding in MtGox?
1. If you want immediate conversion to fiat, they mostly use BitPay or Coinbase, not Gox
2. If they want to expense in BTC, they'll probably hold coins themselves e.g. blockchain.info where you control the private keys
Also, withdrawals were delayed for a long time, hopefully most businesses wouldn't want to live with that and moved their funds out, if at all they were thinking otherwise.
