No one really knew who was behind Bitconnect which is a huge red flag! I doubt that many Bitconnect investors will get their money back, however I think those behind Bitconnect as well as its prolific promoters should be held to account. There should be consequences for their actions.
And then for those who haven't invested in Bitconnect but thinking of investing in other lending platforms, they should use what happened to Bitconnect to make them think twice.
I have outlined some potential strategies to make some money from the lending platforms that are still running, eg Davor, Lendconnect, Thorncoin, here, however those strategies are very high risk and most like result in losses.
