I dont even see the reason why they do create and hoping about recovering up funds or making a solution to those people who lose up funds with the exchange.Tracing it up would really takes time and it do really needs extreme effort and investigation by authorities to trace up for those people who are responsible for this.
If you want to scam people by conducting some scam ICO and run away, you can get away with that. Very hard to stop & prevent. If you have an exchange and you want to continue to make money with it, your reputation is everything. There are several people including myself who lost enough or a considerable amount of money and who are willing to go far into this. Doing this through the authorities may be the last resort. But continuos scamming people who happen all (or most of them) to be in the same forum is a very very bad idea. If we don't get our money back there will be a sh*tstorm of bad reviews, signatures, threads, bulk postings with fake addresses in their trollbox and much much more. It will be in their financial interest to pay us back or they will lose a lot of customers. We are just getting started. Don't f*ck around with computernerds when your income depends on trust & reputation on the internet.
Its always been advised for countless times about storing up big amounts on exchangers shouldnt be done because there would always be a risk.
Who said anything about holding coins for a long time on an exchange? I happen to have send some coins to my deposit in order to trade on Liqui and they never arrived. That is by my knowledge still very normal behavior in crypto. Don't assume things you don't know anything about.
