It is good to hear such news.
Widely accepting bitcoin will lead finally to accept all the altcoins one day.
Now the question is when this day will come?

BTC is the father of all altcoins, when BTC accepted world wide, some AltCoin will follow BTC wins.
Honestly some trusted company only want to accept BTC only for their payment. (for now)
As each day passes, I am more and more disappointed by the alts. Even the most innovative ones that were proclaiming themselves as the new Bitcoin 2.0 kings as Bitshares, NXT, Ethereum are doing very bad and are running out of funds. The most amazing thing is that nobody really wants them and their price is tanking further and further.
More and more I come to a conclusion that world ain't ready even for Bitcoin and not for some alts out there that have barely 10,000 users, no matter how innovative they are.
There is no reason to be disappointed. What is happening in the altcoin world is sheer madness! Way too many, and people actually believe they are part of something great. Might as well buy a lottery ticket. Very few alts will follow suit. Maybe 1-3 of the innovative ones will, but only if they can survive a few more massive altcoin-selloffs.
