All working class citizens should buy and hold $1000 worth of Bitcoin in an account or cold storage device like a Trezor.
You don't have to buy a whole Bitcoin for whatever price 1 whole Bitcoin is going for now, you can buy a piece of a Bitcoin known as Satoshi's.
Bitcoin is the most important asset ALL citizens should be trying to purchase RIGHT NOW. Buying $1000 worth of Bitcoin ASAP might turn into life improving or life changing money 5 to 10 years from now.
This is not investment advice. Do with my opinion as you choose.
