Yeah, now seems one of the worst times for buyers as the price has skyrocketed recently.
I'm going to get my hands on a 1 BTC Gilt again since I sold mine last year, but this time I'll force myself to keep it and not sell it.
In terms of BTC premiums, there has never been a better time for a buyer to get in on a Casascius. This coin (Silver/Gilt) was selling regularly around 3 BTC in late 2015 / early 2016. Now, it would be closer to 2 BTC. Granted, in fiat, the price has gone up considerably. I guess it depends on your entry price for BTC more than anything.
