If you do have this much money tied up in Bitcoin, though, you may want a more secure space to store it. If this is the case, Coinbase offers a Coinbase vault, which has time-delayed withdrawals (giving you 48 hours to cancel a withdrawal) and the option of multiple approvers, increasing security by ensuring that all withdrawals are approved by multiple people. They also offer a multisig vault, which is basically an even more involved and more secure vault, requiring multiple keys to unlock.

(((?'Open'<)[^<>]*)+((?'Close-Open'>)[^<>]*)+)* Match zero or more occurrences of the following pattern: one or more occurrences of a left angle bracket, followed by zero or more non-angle bracket characters, followed by one or more occurrences of a right angle bracket, followed by zero or more occurrences of non-angle brackets.

(?(Open)(?!)) If the Open group exists, abandon the match if an empty string can be matched, but do not advance the position of the regular expression engine in the string. This is a zero-width negative lookahead assertion. Because an empty string is always implicitly present in an input string, this match always fails. Failure of this match indicates that the angle brackets are not balanced.
In essence, Bitcoin futures represent an agreement to sell or buy a certain amount of an asset on a particular day at a price that was fixed beforehand, and to that extent, they are no different from any other derivative financial instrument of the kind, be it futures for corn, oil or soybeans. Companies and businesses buy futures to fix the price for a specific time period, which gives them the luxury of price stability even on volatile markets, while investors often use futures for hedging risks or speculations as the value of the futures contracts is based on the overall performance of an underlying asset.
