Here are few advices that I can give you.
1. Bitcoin past history always repeat or rhymes, find a bitcoin chart and zoom out, you will see that since Bitcoin was born it has always do very well with time.
2. With Bitcoin, only the patient dog eats the fattest bones, don't be in hurry for profits, the time will come when the time is right.
3. I hope you have a job or your own source of income? Beginners who got fed up with Bitcoin investment are always those who invest money that are meant for other things, invest only some percentage from what you are making, weekly or monthly.
4. Read the third advice again, Bitcoin investment is not a short way to make money, only holders makes the best returns, you will need some patience and that's why buying some Bitcoin weekly or monthly depending on how much you can afford is best.
There are things you need to know before buying your first Bitcoin.
There are right and wrong Bitcoin wallets out there, I don't want to complicate things for you.
If you have no money, I suggest you go for Electrum wallet or Unstoppable wallet.

Keep your recovery seed safe (12 words or 24 words ).
This is the key to your Bitcoin, if lost or seen by others, they will drain your wallet.
Keep them offline, away from cloud storage or any devices using the internet.
I suggest you write them down on a steel using sharp object or in a book, do not let another eyes that's not your set on those words.
