I said ASIC.
None of you seem to understand the cost to produce an ASIC.
You also don't seem to realize the risk averse nature of capital holders, and the Bitcoin market is shit compared to other investment opportunities.
Bitcoin is a scam. No-one in their right mind is going to spend any significant amount of money to see the scam through to it's completion.
The market cap of bitcoin is over 60M USD. Since more than half the coins ever to be made are still yet to be made, it is completely feasible that a group of people will want to mine/spend the 1.2M USD capital needed in producing an ASIC miner.
100% return of investment could easily be reached in one year... even if the bitcoin price drops to $1.
