Max Keiser, a prominent Bitcoin maximalist and advisor to El Salvador President Nayib Bukele, has ignited a firestorm within the crypto community with his scathing attack on Cardano (ADA), labeling it “extremely dangerous” and “centralized garbage.”

Keiser’s assault on Cardano commenced last Friday with a tweet declaring that only Bitcoin maximalists would be granted entry into El Salvador, leaving no room for non-Bitcoiners. He then proceeded to share a provocative video captioned “Charles Hoskinson forking ADA/Cardano,” further fueling the flames of controversy.

The Cardano community responded with a barrage of criticism, vehemently denouncing Keiser’s remarks. Unfazed by the backlash, Keiser escalated his attacks on Saturday, asserting that Cardano and other altcoins are “rightly considered toxic, poisonous, unregistered, illegal shitcoins in El Salvador.”

As the debate intensified on social media, one user confronted Keiser, suggesting that his relentless focus on Cardano implied a deeper concern. Keiser responded by cautioning the public about Cardano’s alleged extreme centralization and lack of value, predicting a 99% decline against Bitcoin in 2024. He attributed his actions, including advocating for Charles Hoskinson’s expulsion from El Salvador to saving lives in the country.

Another user questioned Keiser’s obsessive focus on Cardano, prompting Keiser to reply, “I feel compelled to warn people. Like Noah and the ark. ADA is extremely dangerous, centralized garbage.”

Keiser’s remarks come just a day after Charles Hoskinson, the founder of Cardano, addressed Bitcoin maximalists, specifically mentioning Keiser. Hoskinson criticized the maximalists’ tendency to label altcoins as scams and their proponents as criminals. According to Hoskinson, Keiser belongs to a group that deems everything except Bitcoin worthless, illegal, and deserving of imprisonment for those involved.

The conflict between Bitcoin maximalists and altcoin supporters is not new, with Keiser being one of the most vocal and outspoken critics of altcoins. In May, Keiser asserted that everything, including Ethereum and XRP, were securities except for Bitcoin. Just over a month ago, he claimed that cryptocurrencies like Cardano and XRP, among other altcoins, had been created by financial terrorists and were “undoubtedly used to fund terrorism.”

As the crypto landscape continues to evolve, clashes of ideology and competition between different projects are likely to persist. However, a majority within the crypto community advocates for harmony and collaboration. This sentiment stems from the recognition that the crypto sector faces significant challenges, including regulations, hacks, and allegations of terrorism funding.


The ongoing tensions between Bitcoin maximalists and altcoin proponents highlight the diverse perspectives and debates within the crypto community. While disagreements are inevitable, a collective effort towards unity and collaboration will be crucial in addressing the challenges faced by the crypto sector and fostering its long-term growth.
