What is Bitcoin?

Bitcoin is a cryptocurrency, a form of electronic cash. It was created in 2009 by an unknown person using the alias Satoshi Nakamoto. to work as a decentralized digital currency without a central bank or single administrator. This means that transactions are made with no middle men, but are verified by network nodes through cryptography methods and recorded in a public distributed ledger called a blockchain.

What are the advantages of betting with Bitcoin?
  • Fast -> With Bitcoin it is possible to send and get money anywhere in the world at any given time. You don’t have to worry about crossing borders, rescheduling for bank holidays, or any other limitations when transferring your money.
  • Safe -> All finalized transactions are available for everyone to verify on the blockchain. Bitcoin protocol cannot be manipulated by any person, organization, or government. This is due to Bitcoin being cryptographically secure.
  • Cheap -> Because there are no middle men, no fees (or very small fees in some places) are deducted from your transactions.
  • Anonymous -> Payments in Bitcoin can be made without one’s personal information being tied to the transactions. Bitcoin also protects against identity theft.
What is mutual betting and why is it better?

Mutual betting is a system in which all bets are placed together in a pool and payoff odds are calculated by sharing the pool among all winning bets.

It remains one of most adrenaline-pumping ways to bet for your favourite teams and prove yourself right. Why? Because the stakes are forever-free from corporate gambling machines and algorithms. At Onehash, the betting stays between humans—an experience you can’t get when the odds are fixed by a computer.

Mutual betting is very simple:

  • A bettor chooses a side to place his bet
  • Every bet made influences the winning multiplier until the pool closes
  • After the match outcome, winners split the pot proportionally to their contribution

Can I bet for something more than just a final result?

Of course. Depending on the event type, you can bet on the different additional outcomes. For example, some of the additional bet options in football include:

  • Correct Score
  • Each team total goals
  • Goals difference
  • Total Goals

Because it is much harder to correctly hit the exact outcomes from those options, betting on them can be highly rewarding. You can develop your own strategy of finding and betting on the additional results - some of them have very big multipliers!
