Could you secure some investor funds to pay back losses to customers now, and payback the investor after your business picks back up?
This would be a possibility if investors interested in helping continue operations show interest. It is certainly something I am thinking about.
Do you have enough funds to cover this loss yourself?
I am having trouble thinking of other options that would allow for trading to resume, without turning to a fractional model, that dont include acquiring new large sums of money.
