MicroStrategy co-founder Michael Saylor's appeal for Bitcoin investors to hold onto their cryptocurrency assets is being put on blast.

“Sell a kidney if you must, but keep the Bitcoin,” Saylor wrote on X Thursday night.

Both Bitcoin and MicroStrategy have ticked slightly upward since Thursday night.

MicroStrategy, much like Bitcoin, is viewed negatively by some online—having both a band of loyal fans and a wave of critics.

But Saylor’s late-night kidney post on Thursday night primarily grabbed the attention of the critics.

"First you told people to max out their credit cards and mortgage their homes to buy Bitcoin. Now you’re telling them to sell off their organs. Have you no shame?" asked stockbroker and longtime Peter Schiff.

"Tell me you’re terrified you’re going to lose everything, without telling me you’re terrified you’re going to lose everything," responded someone else.

"Bearish tweet reeking of copium," another commenter quipped.

But some of Saylor’s fans went to bat for the entrepreneur.

"If they maxed their CC and sold their house when he said so they would be in massive gains and rolling in dough. But they didn’t and now they’re panicking and blaming someone else for their poor decisions yet again," one such person countered.

"Bitcoin will recover. Hard to think 100k was the top in this cycle. We’ll see new highs yet again!" another poster commented.

Other commenters appeared to be scoffing at Saylor’s post with ironic replies.

"I mortgaged my home to buy more Bitcoin Michael… please tell me it’ll be okay. My family is worried about me. I'm starting to feel fear and panic. Help me persevere! We can't give in now! They'll never see us poor and weak!" wrote one user whose bio describes himself as a "famous troll."

"I already sold one of my Kidney and I need the other to survive ,,, come on guys we can do it ,,,last push to 100k$, " joked another poster.

"What if you already sold both kidneys for Bitcoin?" asked another account. It seems like there's an unsaid "if you're reading this" at the end of this message.

It’s not the first time Saylor has jokingly promoted somewhat extreme measures to push his advice about buying Bitcoin during drops.

On Tuesday, Saylor posted an AI-generated image of himself working as a fast food worker, captioning it: “Considering a second job to acquire more Bitcoin.”

And in January, he similarly advocated that Bitcoin’s “volatility is a gift to the faithful.”

Since that post, Bitcoin has fallen over 20%.
