Twitter's chief executive Jack Dorsey is convinced bitcoin is the future. Dorsey has vowed to help bitcoin development through his payments company, Square—which said it's "only a matter of time until instant, low-fee bitcoin payments are as common as cash used to be." Square Crypto, which was created last year by Dorsey to spearhead bitcoin and cryptocurrency development at the company, has said it is focusing on Lightning and building a development kit for bitcoin's Lightning network.

The cryptocurrency project TRON claims that Buffett is actually optimistic about blockchain technology and believes it will be disruptive. Calling it “an honor,” TRON CEO and Founder, Justin Sun told reporters that he will “take Mr. Buffett’s advice and guidance and make TRON a better ecosystem.”
