Bitcoin (CRYPTO: BTC) reached a new high amid the momentum imparted by the launch of the first U.S. Bitcoin futures-based ETF, ProShares Bitcoin Strategy ETF (ARCA: BITO).

What Happened: Bitcoin-backer and Twitter Inc (NASDAQ:TWTR) co-founder and CEO Jack Dorsey tweeted a cryptic number “705742” Tuesday afternoon amid Bitcoin’s surge. The lack of any other details in the tweet set in motion a guessing game among Twitterati. Dorsey complicated matters further with a threaded reply to his own that said: “off by 117.”

A Twitter user asked if the number was Bitcoin’s price target. Another suggested it is the price of Bitcoin a year from now.

The number Dorsey tweeted may be farfetched if it is meant to be the near-term price target for Bitcoin. A survey of crypto industry experts by has put the year-end price target of Bitcoin at $80,000. Fund manager and Ark Invest founder Cathie Wood has had a long-term price target of $500,000 for Bitcoin.
