From a stealth perspective, I find gold/silver to be more stealth to exchange for fiat currency than bitcoin.
Example: You can buy/sell precious metals for cash in person without registering for any site or showing ID (depending on amount)
Things are trickier for bitcoin, but most of the time you will need to register for a website to exchange your fiat for bitcoin.
From an investment standpoint, bitcoin is obviously one of the best investments from 2014 - present day. However, Bitcoin could be cracked by quantum computing one day, and if that happens the value of btc will tumble far greater than we've ever seen.
If the Quantum issue is resolved I would have no issue holding bitcoin for the next 5 years+
Good points overall. I've used paypal to bank and cash in person for selling BTC. Haven't sold any metals yet.
Quantum is not the big issue to bitcoin that many make it out to be. The proof of work algorithm is exchangeable. This has been debated once because of ASICS but ultimately the ASIC method was given the favor. If the encryption should ever be cracked, there is a direct need to change the PoW to quantum resistant, and it will probably happen immediately.
If Bitcoin is ever cracked I see no reason why the value would not go to $0. I just hope the issue is addressed before it is a real issue.
