But those that shorted Bitcoin have done very well.
If you remember Moore's law it states that - "observation that the number of transistors in a dense integrated circuit doubles about every two years. Moore's law is an observation and projection of a historical trend".
But that changed as the time to double the integrated circuit. And it was an observation not a Law of Physics.
The Crypto winter is another observation not a Law - Quantum computing is coming close to being a reality.
"In the case of blockchain systems, the cryptography protecting their tamper-proof ledgers may be at risk. Researchers at the University of Sussex estimated in February that a quantum computer with 1.9 billion qubits could essentially crack the encryption safeguarding Bitcoin within a mere 10 minutes."
That will change all of the current "Crypto Winter" etc observations.
Bitcoin is being treated as a security not a currency.
The SEC regulating crypto - will have unintended consequences.
At this time your crypto/money is not safe - as there are data breaches every week.
