Bitcoin is going to be in some difficulties in 2017, when Ethereum goes to Proof-of-Stake.
During 2016, Ethereum popularity with new peoples and a younger generation has brought millions of new dollars, euros, pounds, yuan, yen, roubles, etc into crypto-sector.
A certain minority of large GPU miners, store there mining profits in Bitcoins or cash out.
A lot of that new cash, has gone into double spiking the Bitcoin price this year - so Bitcoins real cash-floating price is around $550, but Ethereum has pushed it up to $700 per a coin.
When ETH goes to Proof-of-Stake, there will be no more extra cash support the Bitcoin price and it will move downwards to a more cash-realistic level.
Already a known date when the shift to POS?
Nope, it is being kept under wraps.
Naturally, when the date is announced: there will be a big price spike if it's really soon or big price drop if it is really far away.
Lot's of short-term speculators will messing up Ethereum's loyal long-term investors' private investment schedules.
I'd guess, the the date of Proof-of-Stake is too financially sensitive to be announced this year.
If I cant mine it.. I wont use it.. POS is just getting the rich richer!
That makes no sense!
You can't mine dollars, pounds, yuan, yen, roubles, euros etc - yet, people still use those currencies.
Then, on the other side of the equation people were able to mine ETH with GPU's for 1 year 6 months.
So, most people wouldn't make such a ridiculous statement, because they've had ample opportunity to mine and build up a decent amount of ETH to use in the long-term.
So with that logic.. only people that have mined for X months will have some.. so new people are SOL......
also, we have to sell the eth to pay for power!
Well, it is not Logic, but I'll assume you are referring to Maths logic, as opposed to the Logic related too philosophy.
In terms of electricity:
As the proportion paid in electricity as percentage of the coin value increases, there is corresponding decrease in profitability - eventually achieving 0 profitability. This is because over-investment in hardware versus affordability of running cost has been miscalculated by the owner of mining rigs. Consequently, they are forced into overselling their mining rewards in coins and this drives the price of the coin downwards towards 0 profitability.
So, with mining with GPU's - over the long-run it will head towards 0 profitability.
The underlying basis of GPU mining, therefore, you approach it in the same fashion as what you can afford to buy comfortable each month with cash for that crypto.
Consequently, nearly all Proof-Of-Work coins can go through long periods of low profitability or 0 profitability in relation to age of the mining hardware and electricity.
Finally, Ethereum has the highest number of new people investing and mining it - it was a one-off investment opportunity.
For the 1st time, in a long time a large number of crypto businesses and entrepreneurs and developers and enthusiasts came together to build a new crypto-currency pre-funded with 28 million dollars, yuan, roubles, yen, euros, etc.
So, that is not going to happen, again, for a very long-time again.
