-Risk of 51% takeover - Bitcoin can esaily be controlled by governments, corporations or maffia with an investment of a few million dollars in ASIC-computers. They can use their 51%+ hashing rate to either screw the network or block some accounts that they dont like. Anyone investing 20 million dollars in ASIC right now will have 90% of the network.
Is this really true ? sounds like something to maybe fear ?
It is the only thing we should fear. Hopefully ASIC will become mainstream before "they" actually think about it.
But Governments are not that stupid.
They maybe even read this post ;(
Oh yes they ARE stupid. If not they were buying bitcoins right now. It will be the money of choice to finance their dark activity.
I read this in some other tread:
"A first world government could launch a 51% attack on Bitcoin, but it would be quite pointless. The blockchain would just be reset back to before the attack happened and a patched client that rendered the 51% attack useless would be released"
Is this possible to reset back, and realese new client
?
