@masterOfDisaster I could see what you are saying happening. The more that I learn about Peercoin, the more I like it. The only thing is that Bitcoin got such a massive head start. It is difficult to see everyone dumping Bitcoin, then switching to Peercoin/NuBits/NuShares. A lot of people have heavily invested into the Bitcoin ecosystem, and inertia is a very powerful thing.
But let’s say that you’re right. Bitcoin’s difficulty will start to drop as people switch from Bitcoin mining to Peercoin/NuShares minting. The price of Bitcoin will go into a death spiral, making even less of an incentive to mine it. Somewhere around the early 2020s, the last Bitcoin miner will shut down. It is possible, but I suspect that if Bitcoin does die, it will be a much slower death. Those who put a lot of money into it will keep trying to revive it. As the difficulty starts to drop, they will buy more to try to prop it up. It will die only when all of the fat cats give up on it. However, for this to happen, merchants also have to give up on Bitcoin. If the Winvlevoss Bitcoin ETF is successfully launched, this will never happen. Once the Wall Street fat cats start investing in Bitcoin, it’s over. Bitcoin won’t be going anywhere.
Here are 400 million reasons why Bitcoin probably won’t fail: https://www.cbinsights.com/blog/bitcoin-startup-funding-2014/
I still believe that Bitcoin, NuBits, NuShares, and Peercoin will co-exist, each providing a slightly different function. I expect that the 500+ crypto-coins that now exist will consolidate down to fewer than 10 or 20, perhaps even as few as 5 to 10.
