If we buy stuff with BTCand the company just sells it for cash right away, it's probably not good for the BTCprice.
What do you think? Will shopping with BTC be good or bad for BTC?
Though is said to hit the mainstream soon but buying of stuff with bitcoin while the company sells it for cash is definitely not good for bitcoin price because it will literally cause some dump in price of bitcoin.
Going to malls, or other establishments using bitcoin as direct payment in exchange of cash might result to a negative effect on bitcoin price, but this may lead to the wide introduction of digital currency to the open public, mainly in the market world. If this happens, no one really knows whether it will create a negative impact on digital currency in general, because proper regulation might takes place, if this happens.
