is creating a wall that makes it harder for BTCto be a universal economic currency. Stores may take 1BTC for a product and in the AM that 1BTC could be valued at .08BTC. Obviously theres a ton of positives to this happening I think more than negatives. I for one hope it does though because USD is getting old 
The volatility of bitcoin has both positive and negative effects. If the value of bitcoin increase within the same period of time that the store hold their One bitcoin they can equally make huge profit at the end. Bitcoin is volatile at the moment because the demand is so high as compare to the supply.
