I recently got my money from MtGox. Apparently yes. Don't get me wrong, you have a point. It's just not about crypto currency at all, and yet you're presenting it as a fault of the technology. The technology is sound, problem is in the humans (ab|mis)using it, or just talking about it. Notice how in crypto scams there usually isn't any actual crypto currency - they simply make a web UI with nice charts. Why? Because their scam wouldn't work if they created an actual crypto currency. A scam exchange is the same thing - you essentially sent money to someone on the internet and they ran away with it. The method of transfer is irrelevant, and you have same options if you wired dollars or sent a crypto transaction. It has nothing to do with the many interesting security methods that modern asymmetric cryptography provides, that are utilized to make trustless transactions and smart contracts work on blockchains - you didn't utilize them at all, you simply transferred all your money away.
