(Bloomberg) — Bitcoin rallied back Monday as investors took advantage of the lowest levels in seven weeks to pile back in.

The rebound reverses a two-week slump that had pushed Bitcoin below its 100-day moving average amid technical warnings from Wall Street and fears of a growing crypto bubble.

Some pinned Monday’s move on a tweet Saturday from billionaire Elon Musk, who in the past has affected prices with his comments on the social platform.

In a potential reference to cryptocurrencies, the Tesla Inc. founder asked “What does the future hodl?”, using a term often seen as meaning “hold on for dear life” that supporters use to refer to buying and holding their digital assets.

After markets closed in New York on Monday, Musk’s Tesla Inc. quarterly results revealed that it spent $1.2 billion on Bitcoin in the first quarter and made $101 million selling it during that period. Musk had disclosed the crypto investment in February and the announcement subsequently helped fuel a red-hot rally for the digital asset.

Cryptocurrency-exposed stocks also rose. Monex Group Inc. gained 7.1%, while Remixpoint Inc. increased 7% and Ceres Inc. added 6.1%. In the U.S., Coinbase Global Inc. gained 4.4%, while Riot Blockchain Inc. jumped
