If you really want to keep some liquid hive, i'd suggest to keep 10-30% in liquid and rest powered up.

When i converted my steem to hive, hive was higher than steem so o got less hive. Now the case is opposite and i believe it is the best time to do it now or near future. Hive already have a lot of investment opportunities like having invested in dcity is like short-term locked because one get in under 3-4 months back whatever invested.

Same there are investment tokens which are a good way to keep liquid and earn dividends as well.
