Alternatively, the US dollar gained ~300% in value against the Lira. You really trust something that volatile?
Turks who chose to trust their monetary savings in Lira are doing terrible. Their savings have been destroyed.
Turks who chose to trust their monetary savings in Dollars are doing ok. They're still getting debased, but slower than their fellow citizens. And relative their fellow citizens, they're doing amazing.
Turks who chose to trust their monetary savings in Bitcoin are doing incredible. They took a risk trusting something that many smart people say is dangerous and isn't worth trusting, and they've been radically rewarded for it. Their savings can't be debased and faith in the currency is only growing, even if it's happening in volatile fits and spurts.
Bitcoin is certainly used for money laundering, but so is every other currency. Banks have repeatedly been caught aiding criminal organizations. You're conflating some people using a tool for bad things with the tool itself being necessarily bad. It's not a good argument.
The bitcoin economy is also made of real people, like myself, who work a real job and pay my taxes, but choose to trust my savings in money that can never be arbitrarily debased by easily corruptible humans.
