- Are faucets worth using to start off?
No.
- What would be the best ways to earn any crypto without purchasing?
Crypto (espectially bitcoin) is money, it just isn't your local government issued money. It isn't any more complicated than that. Here, let me re-phrase your question for you.
"What would be the best ways to earn any foreign currency without exchanging my local currency?"
TANSTAAFL
You can provide a product or service desired by others in exchange for payment in bitcoin.
You can exchange your local government issued currency for bitcoin.
You can beg for people to give you their hard earned money out of the generosity of their hearts.
You can steal it or scam for it.
- Is BTCitcoin "just a fad that will die soon"?
Some people think so. Some people disagree.
Bitcoin is a highly volatile, risky, experiment in the decentralization of electronic value transfer. Many think this is as revolutionary today as the internet was in the early 1980's. It is impossible to predict the future.
- How come the price of BTCitcoin fluctuates so much?
Understanding that price is determined by the market forces of supply and demand:
The release of new supply is on a predictable and reliable schedule. Therefore, price is very sensitive to changes in demand. It is still quite young, and being discovered by people that have never heard of it previously. Enthusiasm and euphoria about the future prospects (as well as market manipulation by those with access to enough money to have a significant effect on demand) can create a demand bubble that drives the price up to unsustainable heights. Dissapointment and depression (as well as market manipulation by those with access to enough money to have a significant effect on demand) can suppress demand driving the price down to unsustainable lows. Over time, as the number of entities (individuals, businesses, goverments, etc) involved grows, the available bitcoins will be spread out thinner providing small groups of individuals and localized demand variations less influence on the market. Perhaps the market may settle into a commonly accepted value.
