A few articles about cryptocurrency.
Mostly as protection against hyper-inflation, crypto is something all preppers should own.
NOTE: Do not get suckered into the "Make $xx,xxx in 7 days with Bitcoin" scams. They are truely scams. They claim that by "mining" crypto, you can make a lot of money when each block gets paid out. This is semi-truthful. Block rewards are paid, and are a lot of money. I am writing this on 25 July 2022, and today's reward is $137,080. What they are not telling you is that there are tens of thousands of computers mining, and the block payout is only given to one computer each block. It's basically a lottery.
Making money by mining usually involves joining a mining pool. Everyone pools their money to buy miner computers... dozens, or even hundreds of machines, all working away. This increases the odds that one of your machines will get the reward. But it also means the payout is shared among all the people in the pool. If there's 1000 people in your pool, you'd get $137.08
Look at it logically. If investing $100 could turn into $1000 in a week... why do they need you? If I could do this, I would take $100 of my own money, and next week I'd have $1000. The following week my $1000 would be $10,000. After three weeks, I'd have $100,000, and after 4 weeks I'd be at a million. After 5 weeks I'd have ten million dollars!
Do you really think I'd need your $100 if I was really making returns like those?
You can make a lot of money investing in crypto. But you do it slowly and surely. Put a few dollars in every paycheck. Have patience. The prices will go up. The prices will go down. Keep putting in your few dollars each week. Over time, your investment should continue to grow (I'm not guaranteeing anything). Over the long term, investments typically double each year. Just buy, and hold.
The typical investment strategy is "buy low, sell high". Great advice, but when is low, and when is high? If you had a crsytal ball, hey, what are you prepping for? You can see the future and make sure you are always in a safe place. Without the crystal ball, trying to time the market is very risky. You may get it right a few times, but sooner or later you will get it wrong, and then you will lose big! Just buy and hold.
