The price of the bitcoin itself is one of the issues why businesses aren't accepting it just like that. Today he invests over 100k dollars into btc, tomorrow the price drops from 1200$ to 900$ and he has lost money, and no one likes loosing money. So, he'll keep it safe and not invest ito btc right now or not so much. I've talked to the few businesses about implementing bitcoin and one issue that all of them stated was the significant price drops and rises.
