I had to write the review first to be sure I wasn't bias for the pros and cons. Ampl is an experimental project like most crypto projects out there.
The mechanism works to try to stabilise the price of the coin everyday to $1. When the price is above $1, $Ampl is paid to holders through what is called a positive rebase, which in a way increases supply and tries to stabilise the coins price back to $1 by a safe ratio. When the price of $Ampl goes below $1, the opposite happens. A negative rebase.
Also, this model seems to have not accounted for "human greed", There is nothing stopping the major investors taking profit and damaging the system. It's a project that relies in part on Trust of other users of the ecosystem and their trading choices.
