How will the power of mining nodes change once all the Bitcoin has been mined? Also, how will the power of mining nodes transform as the block reward becomes less and less?
If there's not enough transaction activity on-chain generating many small fees in balance with frictionless value exchange utility etc. Bitcoin will die.
So as the block reward lessens the miners will seek profit from trx. fees. If the trx. fees do not make them a great enough profit to justify running the machinery then game over.
Would u say then. that this is why companies like CoinGeek & nChain are advocating for 0-fee trxs. in order to maybe lure in new users and spark more on-chain activity. Prep. 4 future.
It's also why the banking cartel has Blockstream and armies of trolls shilling(and price pumping) for bad solutions and attacking CoinGeek, nChain and bitcoin.com. No adoption = death
That's THE reason they're doing it. Bitcoin is like a living organism. Earliest growth stages need to go well or it'll never make it to a thriving adulthood. It's not a honey badger.
