In terms of cost ask yourself first if 5m can get you the land you desire presently, land is valuable now and viewing the cost you can’t get much plot except you stay in a rural area where land is not costly for example comparing land cost in lekki obviously investors living in that region started with a huge amount. Bitcoin investment at the other hand is not guarantee, investors hold with the hope of getting a good profit during the long run definitely bitcoin has proven to be profitable. The decision is left for an investor but, both land and bitcoin are highly profitable although having an advantage doesn’t mean an investor will not encounter challenges mostly in Nigeria presently land investors face challenges like flood, which might sometimes discourage a buyer. Like others mentioned investing in both is the right decision still not with a low budget.
