Maybe faucets are waste of time for many people
Time spent - money earned - faucets are waste of time for everyone.
but it can be good for newbies. By using faucets they become familiar with Bitcoin and earning first dollars which they can invest somewhere.
If there were no faucets no one would known how to use bitcoin?
Many of newbies starting without having money to buy btc
They don't have 10$ to buy few satoshi?
Mining requires quite big investment and knowledge, so it's not for newbies.
This is bullshit and not true. Mining doesn't need big investment, you can always buy old GPU's and mine altcoins which many are doing. It is far better than doing faucets.
What kind of knowledge are you talking about? They can't read and do research about mining? It's called laziness.
They also can't participate in signature campaigns, because there aren't many campaigns accepting newbies and due to lack of knowledge they can't make good quality posts.
Newbie need 1 month and 30 posts to become junior member and join bounty campaign.
You can basically learn new language in a month or two, i don't see how hard can it be to do research about bitcoin and altcoins in that time and write quality posts.
Trading can be goid option if they have money for investment.
Hardly newbies can trade with money collected from faucet. First month they will collect money just to pay fees. Oh, wait, did I said a month?
By that time they become junior members here, did research and know things about bitcoin. They don't need faucets anymore because they already know something, right? Do you see how ridiculous is to say that newbies need faucet to learn about bitcoin nowadays?
