Though it is fairly obvious what has happened at The Rock Trading exchange and it is inevitable they will face scrutiny, investors have to ask themselves why they allowed their crypto to be deposited at any exchange rather than on their own devices such as desktop software. Every now and again an exchange falls in to trouble and investors regret their actions only after the event but by then it is too late to do anything about it.
Apart from the manner in which they withheld funds belonging to Coinfan, The Rock Trading had a very good reputation in this forum and if they had managed to return the funds in a manner that was acceptable to both Coinfan and Rock Trading, then they both could have moved on. Exactly what happened at Rock Trading can only be explained after their CFO (eliale) posts to explain or after the Italian authorities put out a statement.
edit:
I was told by an italian trader, that Andrea told him the opposite, that all money would be stuck at international bank.
So this is clear sign of lies and I think legal actions must be taken.
If there have been problems with finances at Rock Trading and they used customer funds/deposits to try to plug those financial holes without consent then there will have to be a legal case to answer and we all would expect criminal charges to be brought against the owners and operators of the exchange.
