Well, I want to believe that you are not from Nigeria and possibly have not heard so much about this country, I am proud of the country I come from but I must say that Nigeria isn't a country that is free from corruption, it is not a country that I can rate as a developed country, alot of things still operates like we are still in 1940 but I trust we are coming gradually..
Land disputes is very common here especially in the rural and fasting developing areas and parts of the country, OP was right when he said he choose peace cus as a land investor in this country, you must have muscle to face land disputes and battles, you must have resources and backing, backing are of different types and the more you have, the better..
Making money is not easy here I don't know about other countries, I am a type of person that don't run away from problems, I face it, fight it and defeat it, what i just have to make sure is that I am fighting a just course, like I said before, I invest in anything I am sure I will make money from, bitcoin, land, gold, where ever I see opportunity..
Of course I am not from Nigeria, that is why I was wondering about the statement that you have made. As I said, with a central registry 99% of land disputes go away. That is why countries have started doing it that way quite some time ago. Once you have a good registry, it itself is mostly free from corruption because it would be hard to make any changes without several layers of corruption. Even then, the original owners have paperwork or proof that would make the corruption go up in flames. It is unfortunate that nobody is working on solving this for you guys since you have many issues of this type as you said. These are the kind of issues that your politicians should be working on. I can only imagine what nonsense they are talking about in their public campaigns and what they are working on? It seems to me that politicians in most countries are doing all sorts of things, except solving the things that need actual solving or that could be solved relatively fast.
No one is forcing you to be a land owner. It's your decision. Just because a government has the power to take your private property for public use, it doesn't make it a bad idea to own land, an apartment, or a house. Those things happen in other countries as well, not just Nigeria. A distant relative of mine lost his house because they built a highway in its vicinity. A concrete pillar was built in its location. He was properly compensated, though, and purchased a better home for that money and in a better location.
Talk about a biased answer. If the miners, developers, or some other entities had the power to take away your Bitcoin from you, that wouldn't make it a bad idea to own Bitcoin?

Whether things can be confiscated from you, and how, is one of the primary determining metrics of whether some investment is worthwhile. If US stocks could be confiscated easily and through corruption, as is land in these cases, the whole stock market would collapse within days -- so yes, it is one of the primary determinants when it comes to investment.
We just have to accept that while Bitcoin is one of the best investments someone could get for themselves, the other opportunities out there too are equally good and when it’s done within the context of the law, you would always get your investments worth come what may. No one is just going to reap you all in the name of the government.
Bitcoin is more about sovereignty and freedom than it is about traditional investing. This is why people who, misguidedly focus on how much they can profit in terms of fiat, miss out on Bitcoin.
