Hello Geenstijl,
i would suggest you to see CLOAK as longterm project. If you had invest only few month ago as CLOAK was only 3-5 cent you would already earn nice profits + staking of cause.
PoSA3 will give you in future more as only 6% staking yearly. As running node (posa3 mixing node) you will get additional 1.8% of sent amount additional.
Don't forget also the tech aspect of PoSA3:
1. Security audit (all small security issues fixed in final version)
2. Trustless anonymous not traceable transaction
We also started already a PR campaign and will work from now much more on it. (not only online PR, real life also look last sponsoring of revision 2016 demoscene) link: http://forum.cloakcoin.com/threads/cloakteam-at-revision-2016.209/
Then we also plan now to start the work on OneMarket Project.
So up to you in what project you want to be involved imo every crypto project is unique.
I wish you good luck in you choice.
peace and love from crypto enthusiast cashmen
