> There's a black market for drugs because people like taking drugs.
Perhaps this is somewhat pedantic, but I think it's more accurate to say that there's a black market for drugs because governments have passed laws to make certain drugs illegal and some groups of people have accepted the risks that come with supplying the demand for this particular market in order to make a profit.
> On the other hand, people only like receiving cryptographic tokens on the assumption that they will be able to exchange them for something in future
It may not be exactly this simple, although this is mostly true. There are those out there that purchase cryptocurrencies to make foreign financial transactions in a way that may be considerably more difficult with their country's accepted currency. This doesn't necessarily have to be an exchange, it could simply be sending said cryptocurrency to a wallet of a relative in a foreign country.
