Bitcoin was created 

 in response to the 2008 financial crisis 

The idea: creating a fixed-supply, peer-to-peer cash system that's not controlled by any single entity would protect people from fallout created by government and institutional financial misconduct.    

 Bitcoin launched in 2009 

 and it's price didn't hit $1 until 2011 

It takes a while for any new idea to get traction, especially when it's complex. It took Bitcoin two years to be valued at $1 and the price continues to climb as people gain more understanding about it.

 Bitcoin's Current Price 

 is listed above 

There are countless reasons to own Bitcoin.
People, banks, hedge funds, and governments are currently invested into it. As adoption and awareness increases, so does Bitcoin's price.  

 there will only be 21 million bitcoin. ever. 

 there are over 51 million, millionaires 

You do the math. The buying power of the dollar has decreased 23% since 2009.  Bitcoin increased 72% in 2021 alone...and there isn't enough of it for even every millionaire to own just one.

 You can buy bitcoin in fractional amounts 

 it's broken down to 8 decimal places 

You need to spend $50k to invest in Bitcoin. The same way a dollar has 2 decimal places ($1.00), Bitcoin has 8, so anyone can acquire it, even if it's little by little. .00000001 Bitcoin is known as a Satoshi.

 Bitcoin isn't going anywhere 

 its total value is over $1 trillion dollars

That's more than Visa and Mastercard...combined. 
People who say that Bitcoin is "going to zero" simply don't understand the technology, its benefits, or how much money has already been invested into it.

 bitcoin is scary for 

 many "old school" financial institutions 

Businesses are charged a fee every time you pay with a credit card. Banks make billions on fees. Remittance companies, like Western Union charge fees to send money. Bitcoin operates outside of those entities.

 the key to bitcoin is decentralization

 it gives you power over your money 

Since Bitcoin isn't controlled by any single bank or government, it has the same value everywhere and you have access to it no matter where you are in the world. The same can't be said for fiat currencies. 

 when you think about it 

 Bitcoin makes a lot of sense 

Think about all the new tech that's made our lives better in recent history. The internet. Smart phones. GPS. Email. The evolution of money isn't something to be skeptical about - it's something to be expected.
