In a way it sorta did. Not directly obviously but if you look at the history of bitcoin, its first truly viable use was darknet markets. After getting established as the currency there, it proved it could work and banks n all started buying it, so it was the weed that did it in a way
I didn’t say anything abt the first purchase so unsure how this is relevant
Edit: excerpt
Silk Road proved the market for secure anonymous transactions based on blockchain ledgers, and the viability of cryptocurrency in general. Before the Silk Road marketplace, Bitcoin was mainly a novelty, with the first Bitcoin transaction famously being 10,000 BTC for 2 pizzas. Shortly after the Silk Road darknet market took off, Bitcoin reached $266 per coin, and the Silk Road marketplace became a $200 million operation.
