I've been scammed too by a Swiss startup but the amount is too small for me to take legal actions. I might end up losing more if I pursue chasing those scumbags. This is a good guide for those who want to get a good fighting chance.
I will not take legal action because the funds I invest are not so big, so if I take the legal path will spend more funds. but thanks for the guides that have been given, it will be very helpful to everyone.
Thanks Memet_52 & Wvizmanos for your comments and sorry about your misadventure.
I edited the post to detail costs associated to each step of the process.
The first 3 steps are reasonably "cheap", so if you have "only" a couple thousands invested it might still be worth the effort.
All the best
