What about enabling instant powerdown has the precondition of configuring a whitelisted address(es)? A whitelisted address could have a mandatory waiting period to change(30 days maybe?) in order to take effect. One could keep their tokens liquid on an exchange while waiting for their whitelisted address to solidify, and once that address or addresses are solid, they could move their funds off the exchange to their account and power up their funds. I think this would solve the security issues surrounding your idea. Unsophisticated users get to keep their training wheels, sophisticated ones have an easy method of exit. I think it would be a good idea for this users to have multiple addresses in their whitelist in case of an exchange hack. Also don't forget, a whitelisted exchange address doesn't mean squat w/o a memo tied to it, so that would have to be part of the system too.
Ya, this would be a great idea. I believe we can find a solution that let's new users keep their training wheels and lets end users swim around during market changes. I slept on the idea of the 5% burn, half going to users powered up and I really like it. Pitched it to a few investor friends and they thought it was a really good idea. It incentives hodling during strong price action because that is when most people will instant powerdown, which can become juicy quickly with a few whales swimming in and out of the market.
Like this idea
