This is what I'm doing currently:
When I'm dropped a new token, I try to decide my level of interest and the level of potential popularity/success of the tribe.
If both are low, I usually sell it and move on. On a couple, I have not and now wish I did. I just don't have enough time or attention to fool with them. If you stake them and decide to get rid of them later, it can be a pain and take a long time to get out!
If one of those things is high and one low, I stake and kind of forget about it.
If both are high, I stake AND actively curate.
In the ones that i have a very high interest I plan on staking, curating, creating, and investing funds.
One of my highest interests is investing, so I have actually stopped powering up STEEM temporarily to throw some funds at LEO. Ironically, it probably makes more investing sense to stay with the base token (if STEEM dies I don't think any tribe will make it), but I gotta go with the passion.
All in all, none of it really matters. None of them cost me a dime initially anyhow :-)
Oh yeah. I did stake and do curate (well...some) CTP ;-)
