Just a thread to ask if how safe /unsafe it is here ? Just like my scripts and Megas

Is there anything special or not known

Always assume everything is unsafe so you use a VM with all sharing disabled, of course VM/Sandbox escapes do happen so you want to keep your hypervisor(VirtualBox/VMWare/Hyper-V/ZEN/Parallels ...etc) updated. Have AV on your host OS also pretty important now a days no matter what.
