So I started using datastore 2 for my saving system.
Quickly saying i used .Changed on cash value and used :Set() to save datastore value
And my question is should i use :Save() function like every 60 seconds or can i fully rely on automatic save on leaving

Just :Set() or :Update(), :Save() yields.
And :Set() and :Update() is reliable since it uses a different cache. No need to use :Save() for every 60 seconds.
Plus, remember to always update DataStore2 when the value is changed.
