I agree with all of the above.
3 to 5 companies doing 90% of the mining will cause death to btc for the above reasons.
BTC is a money substitute for investors. Once a few companies do all the mining they control all the new transactions.
How would you want to hold 100,000 coins and not be able to move them because BITFURY held up the block they are in.
If we get to:
KNC
BITFURY
SP-TECH
AVALON
BITMAINTECH
ASICMINER
all self miners and the rest of the world shut out the system dies.
SP-Tech does have the idea for 5 or 6 people to share a few dozen 16kwatt units in low power areas.
At least it is something. I would want a piece of it maybe.
Killing off the home miner is a moron move. Making the home miner have heater/bitcoin device is viable. All across the world people use this item.
I posted response to something similar in SPT thread and repost here;
I totally agree. Who would invest in bitcoin knowing that 3-4 monopolists can move the price tenfold down just trying to crush each other. Or, how about making transaction cost moving from 2c to $2? Apple is doing pretty good with mass produced $200-500 devices. We just need to find either second use (heat, of course) or other application (in dual use device).
It is very frustrating I have been preaching the above for so long.
I live in the northeastern part of the USA New Jersey.
It has been cold real cold for the last few months. I know of 3 homes that a pipe froze. Not me my coldest room is 77f why? miners.
The avalon 4.1 is the closest piece of gear to use as a home heater. It can go as low as 244 watts running 500gh or up to 700 watts running 1th all very quiet.
Take out that 20% of the hashrate the little guy the 1th to 20th in a garage guy.
Turn it into 100,000 homes around the world with an avalon 4.1 space heater miner
That would be 50ph on low setting and 100ph on high setting. The item can sell.
