As I have pointed out numerous times the best way is to compete directly with the banks
Investors are always looking for a safe haven where they can store and grow their value assets
they also will use these assets and then replace them when and if needs occur, hence banking gets away
with what it does.
at the moment banking is on its knees with most offereing 1 to 2%
but thta can easily be and has been as high as 5-8% so therefore 10%
is reasonable and attractive, it will allow the coin to retain a reasonably long distribution of 15 to 25 years
and lets face it whole countries and societies rise and fall in the space of 25 years these days so anything longer
than that is just a waste of time as no doubt the world would have moved onto infinte other ways of doing things by then.
See that's part of the problem; you can not compare cryptocoin staking interest with interest in a fiat-money bank. That's worse than comparing interest rates from different currencies: As an example 10% interest rate per annum of Russian Ruble is a totally different thing than 10% interest rate of Swiss Franc. Gold doesn't produce interest, but a gold-coin's buy-power is relatively stable over time. Euro and dollar are artificially kept alive, and I'm not sure if even 20% interest rate would turn me into a believer. It's all floating..
The interest rate from Sync won't be worth anything at all if everyone gets it and if investors at the same time considers our total market capacity the same.. What we do instead is that we take value from the people that are not bag-holders by making their money less rare, and give it to the people that are bag-holders!
What we can achieve by rewarding bag-holders only, is that much of the coins will be held away from the exchanges and it will be very easy to pump. As a bonus. we'll keep wallets online as much as possible maintaining the network and securing efficient transactions. That's all! And if you paid 125$ for one SYNC today, you might still get only 125$ for the 2 SYNC you have after a few years, perhaps even less... unless we make people believe in Sync and it's future value, by pumping on the exchange and at the same time writing buttery words in forums and elsewhere.
Interest and Interest can be very different things.
OPEC coin is giving 2% staking interest. Not per year:
Per month!Perhaps those are the ones we should compete with about investors money and not the type of investors that would save fiat money in banks?
It's still only numbers, but it's a lot of psychology in those numbers.
