Exciting times for HIVE and crypto in general!
We have seen these 1 day Hive price spikes before. But I do believe we will be back over 50 cents, and then 1 dollar, during this bull market. So I won't be selling much at all quite yet.
To answer your question
Should I HODL Liquid HIVE & How much is sufficient?
Since I see 50 cents to a dollar HIVE coming "soon" I will keep most of my HIVE as HP for now. But it is reasonable to take profits when they are there, so converting 10 percent of one's HP to Liquid HIVE for eventual sale at a target price can be justified.
The more other people who are voting for posts power down to get liquid Hive, the more the HP holders' Up Votes are worth in curation, so there is that angle to ponder.
Just my opinion and not financial advice! Have a nice day :)
