(Reuters) - Elon Musk on Sunday asked about the possibility of converting “large transactions” of Tesla Inc’s balance sheet into bitcoin, according to a Twitter exchange between Musk and a well-known advocate for the digital currency. Michael Saylor, chief executive officer of MicroStrategy Inc, in a tweet to Musk, suggested that the billionaire Tesla founder and head, make the move. “If you want to do your shareholders a $100 billion favor, convert the $TSLA balance sheet from USD to #BTC,” Saylor wrote in his tweet. “Other firms on the S&P 500 would follow your lead & in time it would grow to become a $1 trillion favor.” “Are such large transactions even possible?” Musk replied to Saylor. “Yes. I have purchased over $1.3 billion in #BTC in past months & would be happy to share my playbook with you offline....,” Saylor tweeted. Tesla and Musk could not be reached for comment. “Every CEO faces the challenge of how to preserve & enhance shareholder value in the face of this year’s unprecedented monetary expansion,” Saylor said in a message to Reuters. “Bitcoin is the best solution to the store of value problem faced by every individual, investor, & corporation on earth,” Saylor said. Shares of Tesla rose to a record high on Friday in a frantic day of trading as investors geared up for the electric carmaker’s much anticipated entrance into the benchmark S&P 500 index on Monday. Bitcoin rose to a high of $24,299.75 on Sunday, after passing the $20,000 milestone for the first time last week, amid surging interest from larger investors. Bitcoin was last at $23,60.98 up 2.88%.
