One of the good things about Twitter (TWTR) is that celebrities and people of influence can react to your opinions about them.
And if you're famous like CNBC's Jim Cramer, the chances that your barbs reach the timeline of the person you're talking about are high. So a response is never too far behind.
DON'T MISS: Elon Musk Takes a Jab at Jim Cramer in Cryptic Tweet
On Friday, Jim Cramer took on one of his favorite issues: cryptocurrency.
"After listening to Tim Massad on last night's show (former head of the CFTC) I would not do business with Binance. Just way too sketchy," Cramer tweeted to his two million followers.
Massad, the former head of the Commodity Futures Trading Commission, has been an advocate of stronger crypto regulations for years. So his bearish stance on the crypto area isn't at all surprising.
Changpeng Zhao, the CEO of Binance -- which is the world's largest crypto exchange -- had a succinct response that is open to interpretation.
CZ, as he is affectionately known, could be thanking Cramer for staying away from Binance. Or he could be invoking the "inverse Cramer" online investing rule that dictates one does the opposite of what Jim Cramer recommends.
CZ went on to brag about how well his company is doing.
No matter the bravado, CZ and Binance do face numerous upcoming regulatory hurdles. But a shot from Cramer could bolster the company's business -- at least in the short term.
