We just need to get sites like Amazon and other big sites to start accepting Crypto Currency!
That will give us a higher price!
Merchant adoption usually results in downward pressure during the short term.
I would disagree. It is correct that many merchants convert their BTC revenue to fiat as soon as they receive it, however before someone can spend BTC at amazon for example they first need to purchase BTC either from a trader, or on an exchange. This creates upward pressure on the price.
Additionally IMO, it is unlikely that someone would buy the exact amount of BTC that they want to spend at amazon for example, they would likely buy more then the total purchase price so they end up with additional bitcoin then they started with (none) after their purchase. This creates a net positive effect on price.
Another point is that when big merchants announce they are accepting bitcoin, it often makes the news, creating additional awareness about bitcoin, and potentially getting additional people to buy bitcoin and spend it places that would not convert it to fiat right away.
