Elon Musk and Dave Portnoy debate Tesla's bitcoin moves

Reacting to news that Tesla (TSLA) sold 10% of its bitcoin (BTC-USD) in Q1 (for a $101M profit), Dave Portnoy takes to Twitter, lambasting Elon Musk for what he sees as a pump and dump scheme. "Bitcoin is exactly who we thought it was. Just don’t be last one #HODLing the bag," says Portnoy.Musk fires back, telling Portnoy he's not sold any of his own bitcoin, and that Tesla only unloaded a small portion "to prove liquidity of Bitcoin as an alternative to holding cash on balance sheet."Bitcoin initially fell a few hundred dollars on the news that one of its big fans had sold, but has recovered most of that drop, now selling at $53.9K.Seeking Alpha's Tesla conference call coverage is here.
