1. Bitcoin is not easily understood by people with no knowledge of it, at such scam and fraud is high on them.
Nobody had a knowledge of bitcoin, everyone learnt. If you do not understand bitcoins, learn from credible sources and not from any person new and even old sometimes.
2. No refund to anyone who incurs loss through keys, seed phase or fraud.
This is why we should be more care every time.
5. Price vitalities - bitcoin price is unpredictable and nobody as monopoly of the market.
The price volatility is also a positive side to bitcoin that many people have benefited.
