What Is BlockChain Trading?

Cryptocurrencies are growing in popularity and becoming more accessible with multiple sources to invest in.
But these digital currencies aren't like tangible assets that rely on a single entity, like a central bank, to define their value.
Instead, they are more like commodities on a stock exchange, as their value relies on a wider community of investors.
That is possible due to 'blockchain' technology, which is a database of transactions, and their subsequent records.
