I suppose you mean "crypto currencies" by "crypto". Usually "crypto" for "cryptography" is the exact opposite of total transparency by being the craft of secret keeping.

But moving past talking semantics .. let's just see what happens when a bunch of crypto currency bubbles burst. Then re-evaluate your statement that people are bot losing their money there. (To be fair, it will happen in the open, and not because of intransparency, which was likely your point.)
