It would make a big difference if some well-known web shops would accept bitcoin as payment option.
But it makes sense that they aren't really interested in a volatile currency like Bitcoin.
Well, not all the big financial institutions are into cryptocurrencies right now simply because there are still options they can make money off in the fiat markets. If they have shown interest in Bitcoin, then the all time high that we saw in Bitcoin already happened a long time ago. We are not going to see big finance go loco on Bitcoin for anytime now even if it is going up. Sure many brokers and traders would be glad to join the FOMO but the big ones won't.
