The price decline is not due to ASIC.
To some extent, it is.
When anyone with a GPU could mine and make some coins, the economy was healthy.
Now, to truly create the aforementioned coins, you need to invest (a lot) in ASICs. Thus, it's not a "for all" game. It's elitist.
An elitist currency is not healthy. It's as simple as that - BTC needs "John Doe" to be able to mine, not only "John Trump".
What Bitcoin was at the start is no longer valid. John Doe is cashing out, and I do not blame him.
