Did you buy 2137.362 LEOMM at around 12K Steem assuming 6 Steem per one? You could have bought 120K LEO and curate to earn couple of times more LEO. Only extra work is curation time which I believe that you are already spending.
However, It is a hard problem to decide buy miner or token with miner's money. In early days of mining (3-5 years back), mining was profitable. But now-a-days, mining is too competitive or trap. I have been mining cryptos from 2013.
Anyway, if Steem spikes close to ATH and LEO doubles or triples, you will make handsome profit in fiat.
In last month, I also went from 4K to 14K LEO. Great to see enthusiasm from fellow LEOian.
