Thanks for your kind reply.

The point is that there might still be a reason to attack the coin even if there is no block reward.
Just to sabotage a project ! To hurt me, to cause harm to me and my work.
To prevent the coin from just working and fulfilling its purpose since someone does not like my project
or simply likes to annoy other people for fun.

So the question is, if the coin is vulnerable / attackable in any way.
Not if there is a reason to do that or not.

I opened up an account on GitHub, installed the app but I am not able to upload my source there.
I am no coder and do not understand the stuff there, I am sorry.
If anyone else might do that for me, I would appreciate it.
