I understand they're only on the testing stage so far, but I didn't know they already rolled out the features to some users. I know it's not final yet, but if they truly do go ahead with their support of Bitcoins, it would be monumental for Bitcoin's long-term outlook. It also seems like Square's stock surged after their announcement, so it's obviously mutually beneficial and shows that people actually want this.
It only takes a few risk-takers for several other companies to want to join the fold, not wanting to miss out on being pioneers.
Yea by testing they mean they rolled it out to a small number of users, not just that its in a testing stage of development, it's actually live for select users now.
And yes this will be monumental for BTCs long term outlook. Other companies will follow suit in order to be competitive with Square and in the near-ish future anyone will be able to use Bitcoin with the payment apps they already own. Hello to an avalanche of demand!
