If enough people speculate for an eternal drop, BTC minting limit will come in as a surprise.
Just come down and let the bulls buy up the whole playground.
IMO, it would be hilarious if that happened; the same market trying to enforce an exponential uptrend, then an exponential downtrend.
At current price, it would cost 18.4 M USD to buy all Bitcoins in existence. If this goes much further, I smell bullshit mode of the funniest kind, especially if short-selling or tactics to "buy back when it rises again" are involved. Good luck sharing those few coins offered for sale at low prices now. A medium-sized real speculator swipes that off in one go if it keeps dropping. Actually, scrap that, any real speculator can already clean up the order book I currently see at least five times.
I'm a sandbox speculator and I know it. Sometimes it looks like Bitcoiners forget. Real speculation starts at 500k on a single move, which means the speculator has access to 10M or more to stabilize against statistics. And those are the small players.
