I think the challenge is the 4 x face value starting price and that these are (I think) still available to buy direct from Kryptowerk - though he has not updated that post in a while so not sure if sold out or some are still available
This is the 2018 box, already sold out from moonbits.
ahh yes in boxes right? but the individual chips might still be available or no? I think I got a 2018 from him earlier this year. but yes, I was not thinking about it being the boxed set. Though I still think 4x face value is a bit high.
