Theoretically possible. You can convert 25K Steem to 200K LEO at 0.125 LEO/Steem. Then you will have 900 LEO VP (2.25x40x10=900 LEO, 2.25 LEO VP for my 5K LEO, ). With curation you can earn 450 LEO= 450x0.125x.25=$14 and then, writing 2 blogs per day with self-vote will earn $17. Assuming you can earn another $3 from fellow investors/traders voting, then $20 is possible. Problem is that 25K SP power down will take 13 weeks and currently there is not enough volume for LEO (10K LEO volume per day in @steem-engine, may be possible with periodic power down of SP and buying for 90 days ). The risk being that LEO fall much below from the buying average say, 0.125 Steem and more LEO get staked, thus reducing the voting power.

Another scenario would be to earn Steem/SBD in passive way with 20% APR from @steemhunt or @ocdb. Then it is around 14 Steem. At 25 cents a Steem, it will be mere $3.5, not even close to $20.

The best case scenario would be to daytrade with Steem in @binance-hot or @hitbtc, then you have to earn 80 Steem per day for $20 (25c a Steem). You only have to increase your portfolio by 0.32 % (less than 0.5%) which is quite reasonable. Even with 5000 Steem it is possible to earn 80 Steem. However, you have to understand the risk with day-trade and spend few hours a day.

However, a trading bot with 10K Steem can do the task. However, I have doubt whether such bot will succeed in the longer term, if the parameters are not tuned. I am personally interested in such bots, let me know if you know ones. However, google search returned me a nice link, I would be interested to know someone's personal experience with the bot (https://coinrule.io/trade/bot-automation/binance/steem-steem/).

I had personal experience with daytrading Primecoin (XRM) in 2013. I used to earn on average 50 XRM from my 3500 XRM for two months.

Another idea would be to manage $25K USD if you are living in US. Then you can earn $200-500 just by spending few hours in Robinhood (with $25K margin off course). Interestingly, when Steem was above $1 few months back (or a year by now), then converting them to USD and daytrading stock would have been the most interesting outcome. Then you could have buy back 25K Steem in few months at this low price!

Best skill in crypto is to when to sell them and when to buy back. Imagine selling 25K Steem even half the ATH price ($4), and buying at 25 cents will give you 400K Steem, then earning $20-30 would have not been an issue with delegating them to few projects. However, you need prophetic epiphany from the @cryptogod to execute such actions.
