i can't say i've seen recent auction results here reflect that. the premiums seem to have dropped dramatically.
Agreed. The premiums have taken a serious nosedive recently.
You could make the case both ways. For example, I sold a 0.1 Silver Cas for 1.65 BTC back when BTC was about $230. Recently they're selling for what, around 0.4 BTC? That 1.55 BTC premium was ~$350 whereas the 0.3 BTC premium now is ~$750.
It's important to note that BTC is destroying EVERYTHING else as an investment and can not be used as a determination of an object's value over time. In the few cases where things have appreciated in BTC terms over this recent rate increase, I would suggest the market is acting irrationally.
Up compared to that dirty dirty fiat. I love seeing Bitcoin finally starting to spread its wings and crush the old status quo. I think now is the best time to be buying physical coins because once we stop reaching new ATH every day the premiums will start heading back up.
