Store of Value & Medium of Exchange are 2 functions of money. They can't be seperated.

I like the way nostr:nprofile1qqsf9jl9scw0c5snmkylpfhkppzgd7z7dupul6ms5yl52kfcz9jr8wqpz3mhxue69uhhyetvv9ujuerpd46hxtnfduq3vamnwvaz7tmjv4kxz7fwwpexjmtpdshxuet5qyv8wumn8ghj7un9d3shjtnndehhyapwwdhkx6tpdsrwnevq describes SoV as Medium of Exchange over time.

Storing your value in a good means that you want to use that good as a medium of exchange in the future.

The most saleable good becomes money.

If you want to be pedantic, gold would have had to have been used as an MoE first. The person that took the gold in the very first gold trade for some reason valued gold more than the good they traded for it. Gold was such a good MoE over time, that people then searched for & accumulated gold so that they could trade in the future with it (SoV).
