why establish a big shareholders club and not let every physical person to participate by locking BTS and reward them brownies (or even better another UIA or even better some bitusd) for doing so in proportion to their bts blocked and time blocked?
If you use another UIA it should still include a percentage of Brownies. I don't know how it would work with another UIA which represents a basket of sharedrop tokens (including Brownies) so I would think Brownies is the easiest way to go about it in the beginning.
Locking 1 M for 1 month and get awarded 50k of Brownies is like receiving something worth c$830 for blocking something worth c$3,330 for 1 month...I know that I would definitely go buy 1m BTS on the market and bock them for 1M if I get awarded 50k Brownies and probably dump them as soon as possible...So I don't think this is a good idea since Brownies will become worthless..
You wouldn't get your Brownies all at once. It should be you'd get them slowly over time just as if you're mining with the maximum over a fixed period of time being 50k. If you're only in it for the dollar amount then you'll dump your Brownies but people only in it for the dollar amount will probably not want to lock up 1 million Bitshares for some period of time.
Also who said it has to be 1 month? The amount of time could have a minimum and a maximum, and be randomly set so that you don't even know for sure if it's going to be 1 month, or more, or less. The length of time could also be a configurable parameter which gets voted on, but in any case once you agree to lock up you can't unlock it prior to the time limit agreed to.
The point is if you dump your Brownies then you dump, but the person who doesn't dump would still have a better reputation than the person who does, and the longest locked holders could get additional UIA sharedrops according to the length of time they locked up. You can basically create an economy around reputation for being a whale supporter of BTS.
I think it would be more normal to earn 5% interest on the bitusd value of the locked BTS. For example, lock 1M BTS for 1 Month will earn c$15 bitusd. The question is from where the bitusd will be found?From the network reserve pool? Is this a good idea?
I don't think you get the point. The goal isn't to pay people USD. The goal is to encourage people to be long term holders by giving them additional future equity, sharedrops, opportunities, rewards, etc. So people who have a reputation for proving they are willing to lock up their Bitshares for long periods of time should be rewarded.
People who just want cash will develop the reputation for immediately cashing out and compared to the people who hold longer, they'd probably not have an equal reputation. So it's kind of like how with Proof of Stake the older coin age means something, the same could be for the amount of time you keep your BTS locked up. If you set it to lock up for 1 month then 50,000 Brownies, and if you go longer than this then you could get priority in sharedrops because people launching new businesses or who are doing sharedrops probably want people who will be willing to lock up and not dump.
