I am happy to tell everyone that I already have collected some nice amount of STEEM POWER (SP) in which a good fraction of it from is from my 100% power-up (SPUD) just even before the spud campaign of 
With some good mass of steem power you can support some people or groups with your effective curation. But this amount you can only give ten 22 cents a day approximately so with that reality and the hard time to earn steem tokens via a normal activity that we do it is just better to 100% power-up because it will get harder to earn it if steem finally would come up with its price.
I am intending to power-up some more to amass a little bit more so that I can earn curation rewards via my manual curation efforts. It is a very good investment strategy while waiting for the steem price to go up and also to wait for the cutting of the time to power down if the SPS about it would get implemented then it is really a good reason to POWERUP because it will hopefully take less time to power-down completely anyway.
STEEM had a lot of great uses and we see it in the creation of Tribes where people is particular niche groups can get together and enjoy their own community so that they can get recognition and support with their works. That is just one aspect of having a lot of steem power or token power with regards to steem-engine communities not to mention apps built on steem which in the future will make more demand for steem which would make it more scarce and finally would raise the price up especially when other projects for steem would arise which could catapult the price in the future.
