EDIT:
After reading Twitter's blog post, I'm even more confused.
Strike is available to people in El Salvador and the U.S. (excluding Hawaii and New York). People in the eligible markets will have to sign up for a Strike account and add their Strike username to receive Bitcoin tips over the Lightning Network. You can use any Bitcoin Lightning wallet to send tips to someone’s Strike account.
Since when does the term "globally" mean U.S. and El Salvador?
