ISTANBUL, TURKEY - OCTOBER 19: People are reflected in screen showing a Bitcoin trading graph in the window of a cryptocurrency exchange office on October 19, 2021 in Istanbul, Turkey. The number of Bitcoin and cryptocurrency exchanges have increased across Istanbul as cryptocurrency investing continues to boom in Turkey. Many investors see cryptocurrency's growth as a shelter against inflation and the depreciating Lira. Turkey's Lira has lost 20% of it's value this year as Bitcoin approaches it's all time high on the back of today's historic debut of the first Bitcoin futures ETF on the NYSE.
