This graph says Bitcoin is up something like 500x since 2013.<p>That isn't a store of time, it is a speculative return. Gold, silver & the US dollar all did pretty much what they are advertised and expected to do (go flat, flat and steady down in value respectively). Nobody knows what Bitcoin is going to do next.<p>What Bitcoin does has nothing to do with storage. Obviously we'd all rather have had Bitcoin from 2013 to 2021 than storage, but hindsight makes these decisions easy.
How about adding the S&P index to the list? That is where many people store their excess earnings (ie. retirement accounts).<p>I know very few people who store their excess income as cash (or Bitcoin, or gold).
