You also need to pay for a US VISA if you're trying to get a B1( visitors VISA) but even going into the embassy it's hard to get approved and that requires you to bring documents and a lot of luck to get the VISA. You basically have to prove that you're not intending to stay there and based on what I see here you wanna live there so it's definitely going to be harder to prove that you won't stay and having prior travel experience and solid assets here in Ethiopia actually really helps your chances. If you are one of the winners of the DV lottery then you will get the VISA but it's an extended VISA that allows you to stay there and maybe even work there, im not very sure here.

What is bad habit

You can't getting a USA visa is a hard process and about the DV its not free you are the one who is going to cover your fee.
