Should I buy bitcoin or not ?

Hello everyone i hope you're doing well.

I randomly had the thought of investing in bitcoin yesterday.

Let me explain : i have a side hustle on prolific and I thought why not use 20 euros each month , or 40 each 2 months to buy bitcoin with. The idea was using the money that i look at and i be like "it won't change anything with my life if i spend it"

It's more like starting small and keeping the habit for some years and having patience and no obligations to sell the bitcoin i would own through the years.

I want your opinions because i really have no knowledge about this, i feel it needs years to familiarise with this field and know what's best for you.

Can you please tell me about your experiences ? Do you advice me to just start ?
