Tesla made billions selling off a significant portion of its Bitcoin stock, but it could have made far more if it waited longer to sell.

Tesla has also yet to prove that its Full Self-Driving software can be used to power a robotaxi network. While the company has been running an invite-only version of its robotaxi service in Austin since June 22, it’s been a far cry from what Musk has spent years teasing.

Tesla and its CEO Elon Musk are walking an increasingly difficult tightrope as the company navigates declining electric vehicle sales and an autonomous driving business that has yet to get off the ground.

Tesla has said it will build cheaper cars and win approval for its self-driving software in Europe this year after seeing sales fall at the sharpest rate in at least a decade. Elon Musk's electric car firm told investors it had started "first builds of a more affordable model in June" while posting a slump in car deliveries and shrinking profits.

Tesla is facing a rough path ahead and will likely struggle unless Elon Musk fixes his public image, longtime investor Ross Gerber says.

Tesla's shares declined 1.74% for week, two days after posting lower profits for a third straight quarter amid increased competition and loss of tax credits.

Nelson downgraded the company’s stock to a neutral rating in April. But even some of the Tesla bulls on Wall Street are saying that the time for Musk to take action is running out.
