It's not just cashed-up dads jumping on cryptocurrencies, juice companies are doing the same too.

Australian juice chain Boost have launched a competition where customers can win one Bitcoin, if they can correctly guess the price of the cryptocurrency at 12 p.m. the following Monday.

Only one person can choose a certain price, to ensure there's no splitting of the prize. At the time of writing, one BTC is equal to $10,569 (A$13,387.76), but as we've seen lately BTC's price has been fluctuating a lot in recent weeks.

Boost will have one BTC a week to win over four weeks. Like any in-store competition you'll need to buy a juice to get an entry code, which you can enter in the chain's app and guess BTC's prospective price.

As for people who might not be following the cryptocurrency rollercoaster, you can also get the app to pick a price for you.

Boost's effort is the latest in a string of cryptocurrency-aligned competitions: There's a puzzle game which lets you win one BTC if you can successfully crack it.

Surely investing in cryptocurrencies is already enough of a game?
