What is Crypto Currency and Bitcoin?
-
What is it? How does it work? How did it arise from the 2008 global financial crisis? How is it analogous to gold? The key to acceptance is attaching a value to it as a medium of exchange. As Bitcoin exploded some were using it for nefarious purposes. Some assumed it was untraceable but Bitcoin depends on the public ledger, the block chain, which is visible on any laptop. It has wallet addresses and transactions. You need wallets, public keys and private keys. A private key is analogous to a signature. Both parties sign off with private keys and bitcoin is transferred.
