It depends on various factors: locality, overall economic well-being, inflation, currency devaluation, expense, financial goals and lifestyle. In third-world countries, a person having one BTC in a wallet will be considered a rich person because the amount is significant in their local currency, while in developed countries, one BTC is equal to just a few months' savings. So, it is subjective to one's country and living standard.
BTC can be considered a good option for investment in the long term and will make you rich in the coming years. It does not matter if you are in a developed country or an underdeveloped country; just accumulate bitcoin for your future.
