ITGS EE - To what extent is cryptocurrency a more practical (overall better) alternative to cash (or credit)?

[snupipupi]

Hi! My research question is "To what extent is cryptocurrency a more practical alternative to cash?

For anyone who can give tips, is there a better way to word this RQ? like adding an "in terms of" or using a different adjective other than "practical", etc?

Also, for anyone who has done a similar EE or has firsthand knowledge and experience on cryptocurrency, please do leave a reply if you have any tips or recommended links, or if we could even have a quick chat as one of my primary resources (having a real hard time looking for any), any help would be greatly appreciated. 

Thank you!
