I have kept nearly all mine and in about 3 months from now I will have withdrawn all the money I deposited. I will still have about 4000€ in current loans and 8500€ in defaults which are recovering about 1000€ in a year. I think it is worth waiting, but it depends on how long you have invested there as the rates are much lower today.
I have now withdrawn all the money I deposited since August 2013.
My next hope is to withdraw enough to cover all the tax I have paid since then to reach break even.
Anything left then will be a real profit but will take years.
