Hungary is a nice quite small country, located in Central Europe from a geographical points of view, and in Eastern Europe from the official UN statistics.
Hitchhiking works generally fine even if quite often people tend not to speak much english resulting in several communication barriers.
Generally good hospitality exchange networks. In main touristic cities (like Budapest) you can also find quite cheap hostels for the equivalent of 5-10€. Malls are a good option to sleep if you find a good spot to hide and sleep.
Usually good availability of both wifi and internet cafes.
Hungarian forint is really not a good currency for busking. Even though people seem appreciate and pay street art, the biggest coin is worth around o.3€ (100forint) while get a banknote is much harder than in neighbouring countries (like Serbia, Ukraine or Romania) where it is normal and common.
