BCH, BSV, BTG, BTC, BTC2, BTCV...What to Invest In?

This time I am answering questions by a listener named Thamzin:

• What is the difference between Bitcoin Vault and LocalBitcoins?
• What are all those different Bitcoin versions that can be found on exchanges or Coinmarketcap?
• How do I know, what a good investment looks like?

No financial advice. Do your own research.
