Are you a miner? You should learn more about mining if you are.
Honestly are the creators of bitcoin core having a laugh?
Are you implying the bitcoin core devs manually set the difficulty? :/
Mining difficulty will be the reason that mining bitcoins becomes impossible. Why can't it be restricted?
Because if difficulty is restricted and the hashing power keeps increasing then there would be block much more often than every 10 minutes on average.
Before all bitcoins have been mined we won't even have the technology to mine them anymore.
Of course there will be. The difficulty is automatically adjusted so that there's a block every 10 minutes with the current hashrate.
Is bitcoins quickly becoming extinct? What would happen if no one can mine a block anymore? Blockchain crash?
Then the difficulty would be automatically reduced so that we keep having a block every 10 minutes on average.
