I have tried to get people to accept it but they also think its overly complicacted, cumbersome and hard to manage and risky
( all of which any new payment would have anyway )
the one person i know who does accept bitcoins is only accepting them as an "investment" (he knows they will be worth more in 5 -10 years than now )but not as a currency
this is another problem ,everybody cant just hoard coins hoping the value goes up ,as addictive as it might be

they have to be traded constantly and thats just not happening enough ,its been said before but if you had a 5 dollar note and a bitcoin in your pocket you would buy your lunch with the 5 dollar note
the bitcoin needs spendability,outside of silkroad and tax evasion if its ever going to fulfill its potential as a serious currency
