I think bitcoin is not supported in some countries because it is not as popular among its citizens and because the popularity is not as much, there are not enough platforms that support transactions using bitcoins or altcoins.  Governments do not see the point of making it a norm in countries like mine because we only have but a fraction of people here who is into bitcoins.  It is because of this that our transactions are very limited to just tradinng and investing.  We have one wallet here or app which lets us convert bitcoins first into cash before we can use to purchase items like prepaid cards or to pay for utilities like water and electricity.  In my country, they are not banning the use of bitcoins but they are not exactly supporting or promoting. it as well so my thought centers around thinking that we have such an old school government that is a bit rigid with technological and financial advancements like cryptocurrencies that's why a change like this is not encouraged at all.
