3. Mining difficulty will increase, but unlike in the past year, ASIC technology will not keep up with the demand for new bitcoins. The new THs miners when they finally appear in late spring will be lucky to generate .5 BTC/day after a few months. I think the mining technology curve is flattening out which will only slow the increase of supply which will in turn drive bitcoin prices up.
Slow the increase of supply? I think you need to do a bit more research into how bitcoin works before i can take your predictive capabilities seriously, even though i agree with $5k and beyond.
