Well people criticize here too much, people who don't actually see bitcoin as a currency criticize very much, its ok to talk about the design but ita wrong to complain about it, for those complaining! anyways i like the  fact everyone wants to accept bitcoin for some goods and services i don't care if someone sells sex toys for bitcoin it actually brings publicity to bitcoin, so whatever anyone wants to sell i guess all bitcoin users should support if they actually need that product, for instance you can buy this for your girl friend instead of using your credit card and buying the same exact thing online... We have to grow out of thinking bitcoin is an investment to hold back and only wait for the BOOM!
