Is it advisable to buy Bitcoin with the little amount I have, or should I rather go for altcoins that my funds can meet up with?.
As a beginner that you are, the best advice I can give you is that you focus on buying bitcoin at the moment, yeah, like you said, the current price of bitcoin may or might seem too expensive, but trust me, the price of bitcoin will continue to grow and get even more and more expensive as time goes on, you don't wanna miss on all the profit that you can make from being invested in bitcoin, most especially, right now that the much anticipated bull run is around the corner.
Altcoins might seem appealing to invest in because they appear cheaper, but trust me, the risk of investing in altcoin is very high, not suitable for a beginner, and also, the chances of investing in the wrong altcoin is also very high, so it's better you just give your attention to bitcoin at the moment, atleast, until you have learnt more and mastered how crypto currencies works, what altcoin project is legit and good to invest in, and one that is not.
This is my honest advice to you, and good luck with whatever or which ever coin later chose to invest in.
