asked a good question of :"What's your go-to for keeping liquid cash growing?" And the best I can say is gear, CDs, tools. SUPRISINGLY my most expensive asset is, get this, my Hormesis Cloudian I was gifted for college graduation. What is that? Well paintball fans may know Hormesis as a headband company that is something like a Gucci of the paintball world. That means that a headwrap can be worth something good. After market on my 1 of 16 Cloudain is worth some 6 to $800. That's correct, a headwrap for a sport can be worth $800. Does that mean you should get headwraps and save? Hell no.
The point I want to make is that if you have a hobby or run in the right circles, it can be worth money to save or buy. How you may ask? To the greater public a headwrap that costs $800 is insanity and that its just a scam. But in the paintball circle that $800 price tag is worth it.
If you are in a niche worth is more subjective than in the general public. Would someone who does do RC car racing want to pay some $300 to get a rare or specialty made internals? Most likely not. But people in the RC community will pay that and more for something they see as worth it. So if you are in a niche hobby then look into groups of that interest and look into buying or trading to get something of high worth inside that community.
Now what if we don't want to deal with niche interest drama and the uncertainty of worth inside of a hobby? Well we have more avenues. You have have seen some online "side hustle" gurus talk about a few avenues of profit like making marriage arches to rent or renting out tools/trailers. Is this worth it? Yes and no.
Like most "Side hustles" you are doing a job/making a business. You need time, effort, and luck set up this "side hustle" to be automated. It can still be very much worth it if you can set up the "Side hustle". This is an avenue where you can make money with varying amounts of involvement on the business.
While I do recommend looking into making a "Side hustle" just remember it is still a job and has a possibility to fail.
Well what's left? Investing in "side hustles" is an option, putting your cash into buying "Side hustles" is about the last thing that comes to my mind. There are always ways to use your liquid cash to make more money like paying for a ghost writer to write stories under your name, programmer to make a game, producer to make music for you, Virtual assistants to help you make an online business.
Just look at yourself and your finances to see what you wan to do. Buy equipment to loan out, buy niche gear to save and gain worth, pay for help on ventures, buy a business, buy equipment to produce more expensive products/provide a service. Whatever you want as long as you have the money and are committed to that path until it can be handed off or automated.
