What did you say 2009 to Bitcoin?
...this thing will end more or less centralized and its no better than [to be filled out; I suggest one of (fiat; gold; precious metals;)]?
The argument brought up by every one of the hundreds of coins here. Conveniently forgetting that Bitcoin had no competition.
Bitcoin was and still is a great invention.
In difference to 2009 Bitcoin now has competition.
And Bitcoin is becoming more and more centralized.
All started with the need for pools to receive an ongoing income for the used hash rate.
It continued with the financial centralization: the need to spend (large) amounts of money for (more and more) specialized hardware (first GPUs, then FPGAs, then ASICs, then ASICs with more and more efficiency in terms of GH/$ and GH/kWh).
It currently is on the way to geographical centralization: mining farms are created where the infrastructure is suficient and electricity costs are low.
One might expect "political" centralization to occur once Bitcoin (mining) becomes banned in certain countries.
I'm glad that Bitcoin started that whole thing.
But I bet that e.g. Peercoin has better chances to survive the next 3 years from now.
What do you think will happen when the coinbase reward for solving a Bitcoin block drops from 25 BT to 12.5 BTC?
The last time the halving occured, Bitcoin was not as industrialized as it now is.
We'll see what happens after block 410,00 (now we are at 323,759 (2014-10-04, 09:21 UTC)).
In approximately 1 year and 234 days from now (depending on the development of the hash rate) we'll face that coinbase reward halving.
But maybe I should stop confusing you with arguments - you already have a belief...
