I agree about the holding part, but right now bitcoin is well knwon for many people and i don't think that McDonald, or any other company that will start accepting bitcoin will infulence its price highly, i mean the price of bitcoin is high and keeps on going even higher, so tehre is no man with the mind is going to go to McDonal and buy a burger for 0.0006 btc, not after what happend with the 10000 btc pizza guy, that amount of bitcoin could be worth 10$ now but in a year or 2months it could be worth 100$, bitcoin is not meant for being used on daily basis, it is an investment that needs to be held and saved until the time is right to collect the profit.
