As an analyst I believe that Bitcoin ETFs could help increase overall cryptocurrency adoption, while also significantly driving their prices upwards. One of the reasons crypto ETFs could lead to a surge in cryptocurrency prices is because they could potentially increase their scarcity and liquidity. Usually, when an asset or store of value becomes scarce, theres a substantial increase in its price. This can be argued too when Bitcoin futures contracts were launched into the market, there will be a more sustainable increase in price. The reason for this is that many investors shifted from the physical crypto market to the derivatives market shortly after Bitcoin futures contracts were introduced. I would attribute the crash that came afterwards to the inexperienced traders who quite didn't understand the supply and demand effects but with Bitcoin ETF signed, investors would be trading Bitcoin and this would also lead to mass adoption and inturn drive prices up.
