Spend some time learning about Crypto - there are millions of YouTube videos that can help get you up to speed.
With so many videos, who should I follow?
A few of my favorites.
What do I use to buy Crypto?
You may need to start with a debit card as some banks and credit cards are blocking crypto payments and transfers.
Where do I buy Crypto?
You buy and trade on an exchange - Here are my affiliate links to exchanges open to US investors - You'll need to create an account and go through the KYC (Know Your Customer) drill of taking pictures of your IDs before you can make your first trade:

How much should I start with?
Start small ($1000 in BTC and/or ETH - $200 in other altcoins) and do your own research until you get comfortable with what you're investing in - make sure you can handle the wild volatility swings with Crypto - BTC regularly drops 25% to 50% in a week - altcoins can drop 90% - you'll be surprised how much this messes with your emotions until you get used to it (probably not until after you have been through a full 4-year market cycle and you're playing with house money)
How high will BTC go?
No one knows but there are lots of opinions - Bitcoin has a 4-year cycle - every 4 years the block reward for finding a new block gets cut in half - Here's a great chart to see the effects of this over the past two cycles - no guarantee this cycle will be the same but it gives you an idea how high BTC could go during this cycle
