What matters the most is that nobody can take my coins from my wallet

Really? So it doesn't matter that the bitcoins in your wallet are now worth about 1/4 of what they were a few months ago?

Where did all that value go? My guess is a lot of it is sitting in fiat bank accounts someplace under the control of Binance and Bitfinex.

The numbers in your wallet may be the same but 3/4's of the value has been removed. You've been robbed and you don't even know it.
