Tesla and Spacex CEO Elon Musk and Twitter and Square CEO Jack Dorsey have agreed to have a discussion at a bitcoin event called “The B Word.”

According to its website, The B Word event will take place on July 21. It is a “Bitcoin focused initiative that aims to demystify and destigmatize mainstream narratives about Bitcoin, explain how institutions can and should embrace it, and raise awareness around areas of the network that need support,” its website details.

Dorsey has been a longtime Bitcoin backer, especially via Square In February, after Bitcoin prices had tumbled, all it took for a strong rally was news that Square had bought 170 million worth of the cryptocurrency. In 2018, he boldly predicted that Bitcoin would be a world currency within 10 years.

Musk, meanwhile, has the preternatural ability to move crypto markets with the vaguest of tweets. Dogecoin’s rise/fall  can, in large part, be credited to his off-the-cuff comments. And Bitcoin’s fall from grace earlier this year was due, in part, to his tweet about Tesla no longer accepting the bitcoin 

Dorsey, who will be a featured speaker at the event, tweeted promoting the event on Thursday. “As more companies and institutions get into the mix, we all want to help protect and spread what makes bitcoin open development so perfect. This day is focused on education and actions to do just that,” the Twitter CEO wrote.
