First, educate yourself and then others.
Best source of Bitcoin is using your savings and then buying bitcoin directly from somebody.
And have a real, normal job, and set aside 20% of your paycheck to buy bitcoin every paycheck period. Otherwise, overtime, you are making yourself poorer compared to the rest of the world.

Here are weekly peer-to-peer localbitcoins cash trade data for two random countries as time goes on. Right-most area is the most recent past week.
Bitcoin is a secure, decentralized, trustless and open system which cannot be banned nor controlled.
Bitcoin is ultimate store of value and its popularity has strengthened over time and maximizes value compared to any other altcoin...why?:
If it can be shutdown, and have assets frozen by a bank or government, there would be no value
If it wasn't secure, there would be no value.
If it wasn't immutable, there would be no value.
If it wasn't globally distributed, there would be no value.
If it wasn't so strong, open-source decentralized and unstoppable, there would be no value.
If it wasn't so scarce, there would be no value.
If it was easy to spam transactions, there would be no value
If it required a central 3rd party to function, there would be no value
If it was stopped after all major banks on Earth banned in 2013 to today, there would be no value. (say "bitcoin" when transacting and watch the block of the transaction. simple fix=never mention "bitcoin").
If it didn't have the history of 8+ years (and still no hacker can exploit bitcoin blockchain), there would be no value
If it was exactly like fiat and only did transactions, there would be no value.
Bitcoin's value is worth hundreds of billions USD today. Altcoins however are scams, weak, pyramid schemes not offering these values.
Bitcoin has all the characteristics needed combined to hold the most value and increasing more than any other financial-asset option coming from the manipulated fiat central-banking debt-system. (more than stocks, more than houses, more than gold)
