What is the best way to start investing in bitcoin?

my firts council, is to you study and understand the principles of the cryptos, why they exist, its not seen only like and investiment.

the you understand why ppl created the cryptos, you'ill be able to know how much money you can "spend/alocate" on crypto.

Minning is a bit harder, if you dont have relevant amounts of money to invest, you will need bet on an specific crypto that you understand and hope for your growth
