Cryptocurrency always has weird exchange rates. That's part of the reason why I brought it up. The way they work is weird as hell.
I'm assuming you are talking about real life crypto and not crypto in the game (is crypto in the game?). And since it's the former, I'm gonna go slightly off-topic with this :
If used properly, buying crypto can net you insane returns. I use Brave to get BAT tokens and I used those BAT tokens to buy tiny amounts of Bitcoin and Chainlink. Now the rates of crypto are rising and the tiny amount of crypto I have got a nice sizable jump.
Now is a bad time to jump into crypto because of the high prices but if you had jumped in when it was really down, that'd have been the perfect time to buy some crypto.
Crypto is a good alternative but it does have its caveats. Volatility is really high, predicting its movement is difficult, and it has significantly more risk than investing in stocks. I'd always recommend you use a small amount of crypto. Don't put your entire life savings into it thinking you're set for life because the chances of that backfiring is extremely high. Buy a small amount of crypto and HODL it till everything increases in price.
