So does anyone really know how long Bitcoin will be viable if mining is completely not worth the money or time because of the exponential increasing in difficulty??
1.3THS 6 months ago at the difficulty of just over 2 billion was yielding over $200 USD a day. Now it takes 12THS at 16+ billion difficulty to get that kind of return.
I'm not financial whiz or mathematician, but unless BitCoin goes up in value to about $100K a BTC, mining will be a wasted effort to just about everyone unless you own a datacenter and are pumping out PetaHashes of power and using some exotic power source that's not costing you a dime to use.
And what's the report that the last BitCoin will be mined in the year 2140?!? Shit!! At the rate the difficulty keeps going up, this digital currency will be dead in 5 years or less.. The only people that will be able to afford it are the same fucking central banker types that have pretty much ruined everyone's life on this planet..
It doesn't matter if you have a datacenter or petahashes. You are still competing with others, as long as you have cheap electricity you should be fine cause people will be shutting down their not so efficient asic soon.
