Money in your wallet don't bring more money so you spend it and it's gone.
So If you try to look for good Investment opportunities early like was doge or shiba even with 2$ wich is nothing to risk you do right thing.
3 golden ways are:staking, Investing and DCA.
If you keep those things going on then it's impossible that you don't earn money when you sleeping.
For staking i have different wallets and on exchangers and different coins
No matter how little you earn by doing nothing but if you can earn it you make more money from money.
My number one thing now is crypto staking on many different exchangers and self custody wallets stablecoins and altcoins.
There's levels to it my friend. While you are definitely right about making your money work for you in the sense of investing it and DCA-ing as you have mentioned, it doesn't necessarily encapsulate the whole process of generating income and wealth. Some people find this success in the form of business, some have it prepared to them by their parents (and there's nothing wrong about it, sure earning your dough is good but just cause little Billy here's got good parents doesn't mean he doesn't deserve any form of success), while some chase it in what you have mentioned, investing and waiting for shit to blow up, skimming off the profits at the top in the process. And other people just choose real estate and profit from the bubble market before it blows up and we all get houses for dirt cheap.
Right now, the most accessible for an average joe is crypto, and I would always swear by choosing which is most accessible for you and easiest to understand, after all, this is where you'll be making your money from in the next couple of years, so you need to be very mindful of shit.
