You can sign up for crypto accounts for free, and if you hunt around you can find faucets (which hand out small amounts of cryptocurrency for free) for many smaller cryptos that are trying to gain visibility. It takes no money whatsoever to switch over to cryptocurrency. (Granted there are many services that charge a fee for convenience or prey on people’s ignorance, but if you are paying much to a middleman you are doing crypto all wrong anyway.)
