Multicurrency in woocommerce without a plugin?

Question

WordPress

Hello.
Interested in how you can make multicurrency in woocommerce without a plugin, if someone in the topic throw a link to an example or tell me where to dig?
The task is to install 5 currencies on the site and display a different price for each currency for unregistered users and those who are logged in. So far I have not found anything suitable from the existing plugins.
Thanks in advance.
