Hello, I would like to test alpha just to see it but since I'm a big noob in all this stuff I hesitate because of my PC security.. is there any chance that by connecting an alpha node someone could steal my files from PC ? someone can explain if it is secure ? thanks !
These alpha or beta testing is normal process in many projects which is completed by people interested in some project. Since these are managed by teams they are not dangerous because no project puts its reputation on stake. It is from official channel so should not be any problem. If you are not sure then for your safety use other machine to participate or stay away and wait for results.
