Can anyone tell me how to start investing in bitcoin because im new in this field
The best method is to buy Bitcoin in small chunks, not the whole 1BTC right away!
But this would need you to wait till a lower price is hit, you might want to take some time to understand how a wallet works, how to keep it safe, then learn about exchanges and trading.
I would suggest you to post a new thread about what you already know and what you need to know so people here can start answering better.
