If the difficulty does not increase, due to the large hashpower of the network, the blocks would be much much faster. This wouldn't allow for the capped supply that Bitcoin features. Orphaned blocks would also be much more often and thus allow for a higher block reorg. We won't ever be see a confirmation to be safe.
I`m not sure about those claims, i`m no expert. So can anybody else confirm or deny this?
It seems plausible at least.
With no or low difficulty, bigger players can still generate blocks much much faster than an average joe. This would benefit them even more.
Low difficulty does not mean that most would be solo mining. People can still use a pool and get similar payouts.
Of course, but the average joe would have larger share for himself. Right now how much can an average joe mine?
1 satoshi/ day? With a low difficulty you could mine as much as a faucet give you for example.
So when newbies still ask on the beginner section how to mine bitcoin wit PC, you could give them a way to join bitcoin for mining.
Nobody knows if the mining dificulty curve is good or bad, perhaps it could have been increasing later.
Bitcoin should have had a bigger inflation in the first years, to attract many people via mining, and much less inflation later when serious developers join it to safeguard funds.
