Hope so. Almost all of them did nothing but fuck the people who put money in.
I presume a legitimised version of sorts will turn up but there's no way regulators will allow what happened in 2017 again.
In the meantime if you have a good idea here's a crazy thought - raise the money conventionally from people who have a clue who expect results and to be convinced. That'll instantly get rid of 99.5% of the people wanting money which is fine by me.
