1. All BitCoins have been generated
2. I'm not longer receiving BitCoins by processing blocks, therefore I'm not longer using my hardware for BitCoin processing.
you're still receiving bitcoins by including fee-containing transactions into your blocks,
it won't be optional
by then anymore, all miners will only include fee-containing transactions,
if you don't pay a fee, it's very likely your transaction will never ever confirm.
3. The network becomes slow and infrastructure gets smaller.
the network doesn't become slower when miners stop mining,
it'll only become weaker
, block-generation will still take about 10min on average.
4. The BitCoin starts to devaluate.
why? did the supply increase magically? or the demand decrease somehow?
5. I want to keep the value of my BitCoins, then I again provide my hardware to keep the value.
good choice, protect your value, don't let the network become weaker.
6. Now, I'm hardware and energy dependant.
aren't you already?
7. The system (Goverments and banks) controlls the BitCoin by increasing or decreasing the hardware and energy cost (in U$S).
why doesn't the system
start trying now?
