Potential new user/invester into Bitcoin

Hello everyone.

Today I was checking Bitcoin, I was never into this kind of matter or interests BUT today I was just browsing the web and checking it out, I'm new in this world and I wish to leanr as I was always curious.

I was impressed when I saw that 1 Bitcoin = 55457,88 €.

I'm interested here about some advice, sound advice if possible, for someone who wishes to get into Bitcoin and start with buying small and eventually grow in time.
Is there anything that I can do? What should I look for on the Bitcoin market and it's fluctuations?
