51% attack, obviously. It is like that when you allow one mining pool to have more than 51% of total hashpower and you have no clue who really is behind that pool. You should at all times asume they will abuse their power and it is so because most people when tempted hardly ever manage to permanently resist the temptation.
Distribute your hashing power so that no pool is even close to 51% of total hashpower.
I don't know if you're trolling, or if you're serious. If you are serious, I have no idea what the hell you're talking about. There's no 51% happening right now. There's no double-spending going on. Plus I don't even mine at 1gh.com (which you're referring to). I've never lost a penny from any pool. This is an EXCHANGE issue, NOT a pool issue.
Today I see on bter if I click MAX deposit: MAX deposit is disabled about 50 maxs are in motion for half day, anyone same issue ?
Same issue here, deposited MAX 5 hours ago (600 confirmations) and zero balance still. Only to find out that MAX deposits have been "disabled" on bter.com.
Does this make sense for an exchange to "disable" deposits, yet post NO announcement of it?
I heard from someone that they got an email response from bter.com stating they need 1000 confirmations now for MAX. What type of bs is that?
