Well, since the halving Bitcoin is up 15% since the halving and has just broken out of a 7 months long accumulation channel. Anything that goes vertical non-stop isn't sustainable and Bitcoin has averaged 28.3% yoy CAGR - even if you bought at the 2017 peak. Has anything else outpaced it?
Literally noone has lost money in bitcoin holding it for longer than 6 years. It has no 3rd party risk other than the US SEC trying to ban something which is now global and being increasingly globally adopted. You have counteis like esalvador buying 1 per day, you have Microstrategy leveraging it's share price increases to buy more of it, there's nothing other than gold that comes close to its scarcity
