All of these mistakes re quite common in crypto newbie world besides faucets. I really do not think anyone sane uses faucets anymore besides people from third world where $1 means something.
On the other hand, these people re not targets for faucets marketing so it does not work.
Why not! Initially newbies can start up with the faucets and then they learn about bitcoin Youtube and another online article which has been mentioned in the above post. Apart from that newbies get scammed in some trades, mostly in Accounts, invites, cloud mining and gift cards.
Please learn everything before get into the services or trade in this forum.
