Hi members of this forum.

I am just starting in crypto stuff and I am a little confused beacuse the overload of information online. I've read that Bitcoin is not what it was used to be, or that mining is not profitable anymore. Also I've read that to make money it is better to work with altcoins.

What would be your advice for someone who does not own any cryptos but want to get some to enter in the crypto trade world?
Is it better to mine alt coins? If so, do you advice on one in specific?
And what is the  fastest way to earn BTC?  I have read that with signature campaigns but I am a newbie so I can't have a signature yet.
Any advice?
Thank you
