Remember unspent funds are one of the key assets Byteball has over the vast majority of other crypto projects. Further you are incorrect in saying the new distribution methods are failures. Most have only been tested on a small scale, and have successfully got new users which is the aim.
nope. they're a liability.

there are other plans such as a set amount for the first however many millions of wallet openers. that makes sense. this cashback stuff and failed id verification handouts are not realistic or pragmatic.
