Trading has been done for centuries. It all started with exchanges, food against clothes, gold against goods. When the first money came up the money was representing the value by its own material. Much later people started to believe in money by itself. So paper money was excepted, but the back up value was stored in huge tresors. The back up resources were melting like the ice in Vikingerland. Believing in values replaced the values. The Bitcoin was born. Krypto Currencies got established. Valhalla is combining crypto technology with traditional company shares. Valhalla is putting the Krypto Coins on top of each company share legally bound and technically secured by blockchain technology. The market for trading is huge. Besides trading of any kind of goods, shares of companies, coins and futures can be traded.
