4) Bitcoin is not a traditional investment, and also the release of new coins is not endless, it is very specific and known values, known by all in advance. No surprises here.
... unless, surprise, the top mining pools decide (with the main developers' blessing) that the next reward halvings need to be postponed for a couple of years, in order to ensure that mining remains profitable and they are not forced to abuse their overwhelming hashpower in nastier ways.
This would kill bitcoin value, this is called suicide.
That well may be, but if you have hangars' worth of gear that could keep mining at a profit @current block reward rate, vs. same hangars worth of gear that's a disposal liability @1/2 the rate...

yeah wow.. I am sure the miners have never considered that.

I'm sure they've considered it, and will act on it once the time is right

BTW, what's with the double-spacing faggiotry? I realize you have nothing to say, making me scroll won't fool me into thinking otherwise.
^That. Who knows what the dev/mining cabal is cooking up for us?
