For some reason, people keep repeating the idea that merchant acceptance will decrease the price of Bitcoin, since merchants will immediately sell any Bitcoin they receive. All those new users dumping Bitcoin will change the market, they say. 100,000 merchants, even.
How many customers will have to buy Bitcoin, in order to buy from 100,000 merchants?
If millions of people immediately dump their fiat for BTC, will the price of fiat decrease relative to Bitcoin?
People buy slowly or sometimes they earn, but merchants dump at a time to pay their expense. Simple.
