You are running out of time to get ahead in cryptocurrency.
You know what's coming:
🔺️ Regulation
🔺️ More shutdowns
🔺️ Banks deciding who gets to do business
It's time you got your own crypto wallet.
Don't know how? I'll show you.

METAMASK
What's metamask? It's a wallet. That you -- I mean YOU -- own.
You see, when you buy crypto through an exchange like CoinBase, you own it but only kind of.
If they get
🔺 Hacked
🔺 Shutdown
🔺 Servers crash
-- your money is STUCK.
We are gonna avoid that 👇
First thing,
Go to
https://t.co/JXAp9o5RzJ
You can download it on your computer. It's a browser extension.
Alternatively, go to the app store on your Android or iPhone. It's there too.
As part of the setup process, you will choose a password.
More importantly though...
SEED PHRASE
As you follow the setup process, you will be given a 12-word seed phrase.
WRITE. THIS. DOWN.
Take it down and guard it like the map to Davey Jones' Locker.
THESE ARE THE ONLY WAY TO RECOVER YOUR ACCOUNT.
DO NOT LOSE.
We good? Great.
Let's continue.
Once you're all setup, your MetaMask wallet is going to look something like the picture below.
See where it says Crypto Address? That's where your actual address will be.
It'll be a random arrangement of letters, numbers, etc.

A brief analysis and comparison of the CSS for Twitter's PWA vs Twitter's legacy desktop website. The difference is dramatic and I'll touch on some reasons why.
Legacy site *downloads* ~630 KB CSS per theme and writing direction.
6,769 rules
9,252 selectors
16.7k declarations
3,370 unique declarations
44 media queries
36 unique colors
50 unique background colors
46 unique font sizes
39 unique z-indices
https://t.co/qyl4Bt1i5x
PWA *incrementally generates* ~30 KB CSS that handles all themes and writing directions.
735 rules
740 selectors
757 declarations
730 unique declarations
0 media queries
11 unique colors
32 unique background colors
15 unique font sizes
7 unique z-indices
https://t.co/w7oNG5KUkJ
The legacy site's CSS is what happens when hundreds of people directly write CSS over many years. Specificity wars, redundancy, a house of cards that can't be fixed. The result is extremely inefficient and error-prone styling that punishes users and developers.
The PWA's CSS is generated on-demand by a JS framework that manages styles and outputs "atomic CSS". The framework can enforce strict constraints and perform optimisations, which is why the CSS is so much smaller and safer. Style conflicts and unbounded CSS growth are avoided.
