I believe that one of the major reasons why cryptocurrency did not gain that fast speed in adoption as it ought to is because of the government restrictions on it over the years. The government as an institution can do it better because they control the nation and the people abide by the constitution, which made it difficult for some nations to adopt cryptocurrency. Now that it is happening, nations are beginning to see the importance of Bitcoin. I think there will be a new wave of adoption across nations, and the Nigerian government has already begun to see the benefit after this long period of scuffling with crypto in the country.
OP, as for your option to choose for a start, I will advise you to start with old coins that have long been in existence. They already have a strong base coupled with market capitalisation, which could be seen via coinmarketcap, and are popular in demand compared to others. As for DOGE, I would not advise you to opt for it as it is a meme and has no utility value, and as a matter of fact, it has nothing as a driving force except Elon Musk backing it.
