Deflation destroys economies by forcing currency holders NOT to spend their money.  It is for this reason that the actual word cryptocurrency is a misnomer because it is not truly a currency at all.  Most of all cash coming into bitcoin is only used as a store of value.  If there is to be an actual cryptocurrency that breaks into the mainstream, it will have to be INFLATIONARY.  This will cause people to use the technology as it was supposed to.  This also has the benefit of keeping the price more stable instead of > 20% fluctuations on a daily basis.
