**Update**Okay so I left v0.16.0 and focused on v0.20.0.
I successfully build v0.20.0 using
this guide, the problem is that I don't know if I have successfully created a new blockchain. When write
getblockcount I get 0. Although it still shows me that I'm connecting to peers. Before I compile I had removed every single line starting with
vSeeds.emplace_back so I don't make sense. I also had changed ports. (8333->6333, 18333->16333)

^ I shouldn't get that peer.
I think I will continue my issues about the altcoin creation on that guide, but if you have anything to say I would really want to know. If I have make a mistake, if I haven't make something important. It would be really helpful. Note that I did not create a genesis block, I left satoshi's genesis block as default since I don't care about the first block. Thus I skipped the entire 12th part of the guide.
Question. Are, the compiled files of bitcoin core on my ubuntu, also usable on a windows system too? If not, is it possible to compile the source files from ubuntu and create the executables for windows?
