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..
Well you are correct your math skills are off by a lot.
we do not need 100k a coin for btc to work.
If btc was 6k a coin the new antminer s-3 would earn more then 4500 usd
If btc was 60k a coin the new antminer s-3 would earn more then 55500 usd
If btc was 100k a coin the new antminer s-3 would earn more then 93300 usd
Your investment of 600 usd would whale smoke fly levitate etc in any of the above btc prices.
So right now in the world we live in a 1 year gain of 20% over money put in is really good..
this means turning 600 into 720 in a year. well lets say btc is high risk. so turn 600 into 780 a 30 % return would satisfy many people.
If btc went to 1040 usd
a s-3 would pay back about 790 usd
so 480 plus about 120 for wires psu gigabyte switch = 600 usd.
(way less if you have all that shit from your s-1's)
So miners need a price jump of 630 to 1040 to do very well make a good 1 year profit.
