I am involved in cryptos. I am mining scrypt based coins. (Mainly litecoin which is like the 'silver' of cryptos, bitcoin being gold). This mess is tanking the entire market. I think it will all sort out over time, but Gox is missing 780,000 bitcoins. ($600,000,000 pre crash value).
Lots of theories, but it could be the result of inside manipulation...tanking the exchange and buying up all the coins cheap. (like shooting fish in a barrel since they froze bitcoin withdraws)
In the end, this is good for me as the LTE:BTC ratio has gone up about 15% even though the overall value is down with bitcoin. If and when things go up, litecoin is poised to make some nice gains.
Also in litecoins favor is the fact that it is not subject to the malleability issue that Gox is blaming on the Bitcoin losses. Litecoins network is much faster at verifying transactions.
