Reiterating a part of my previous reply to you and wording it differently:
A currency's inflation rate compared to BTC should be the eventual slope of its falling channel in terms of BTC.
So a drop of an inflationary currency in BTC terms does not imply that it became a better buying opportunity.
Since many currencies have varying inflation rates (in some sense all currencies have varying inflation rates) it becomes more complicated and less linear, but still possible and not too difficult to account for.

After I resteemed t due to the downvote I regretted doing so, because your question implicitly hints that Steem is a benchmark for profitability.
Had you been an aggressive, and not necessarily malicious dolphin or orca or whatever your amount of Steem is, you would have made more on it, and been able to deter the likes of themarkymark.
I see dolphin sized users that are still being bullied, but they do not play the game the way they should, or otherwise themarkymark would have gradually shrank at least compared to the totality of Steem in existence.
