In a Twitter debate on Mar. 2, Cuban, who has become increasingly sympathetic to crypto, warned Peter Schiff that gold "will die" as a store of value (SOV).
Cuban to Schiff: "Gold is dead, move on"
Schiff, a gold bug who has long made a name for himself as a firm Bitcoin skeptic, continues to tweet disparaging comments about the phenomenon despite BTC/USD regularly hitting new all-time highs.
Responding to remarks about Wall Street firms being "dumb" by buying it, Cuban offered a dose of surprisingly pro-Bitcoin medicine.
"Let me help Peter. Gold is hyped as much as Crypto. Do we really need gold jewelry? Gold can make you a ring," one tweet reads.
"BTC/Eth are technologies that can make you a banker, allow friction free exchange of value and are extensible into an unlimited range of biz and personal applications."
Continuing, he gave a stark verdict on the future of gold.
"What we are seeing built w/crypto today is just proof of concept. As tech continues to get better/cheaper/faster there will be new applications and maybe even something that supersedes what we know as crypto today," a further post says.
"But Gold won't ever change. Which is why it will die as a SOV."
Cuban had formally given little time to Bitcoin or cryptocurrency technology more broadly, sparking a concerted effort among proponents to persuade him to reconsider. In January, he revealed that he still had holdings from years ago which he had "never sold."
"Don't forget, Gold was a SOV built on technology. From picks and shovels to mining operations that keep trying to improve. Whoever could use the tech of the day to find and mine the most efficiently was the most rewarded. Much like Crypto is today," a final message to Schiff concludes.
Gold is dead Peter. Move on."
Schiff had little to counteract his words, calling cryptocurrency a "malinvestment" and arguing that gold could back digital currency in future.
If you can't beat 'em, trade 'em
Meanwhile, Schiff's years of scorn have found a new, more productive purpose.
As many joke that his Twitter posts serve as an indication of Bitcoin price bottoms, one trader revealed a homemade trading tool that has spent a year performing transactions based solely on Schiff's social media activity.
"Since May, the algorithm would have executed 203 trades, achieving an annualized return of ~1000%," Sam Baker, a student at Boston College said, uploading a sample of its profits.
"65% of trades are profitable with a 3% average return."
"I guess that's as good a reason as any to buy Bitcoin. Good luck," Schiff replied.
