Let me get this clear: are you asking whether you should buy a link-building network with your money or invest in crypto?
If I got your question right, the answer depends on your risk tolerance.
Many people are under the impression that if they build a link-building network that it's pretty much-guaranteed money in the bank.
Nothing could be farther from the truth.
There are parts in this type of plan that can break down.
For example, you have to find the right domains, build your network correctly, link correctly; there are just so many different things to worry about.
The same goes with investing in crypto.
Unless you're investing in venture-backed projects with a track record and are fast-evolving, your chances of losing money in the crypto space are quite high.
This is especially true if you invest based on hot trends.
You have to understand there's a lot of scammers in the crypto space.
These scammers think that a certain trend, the metaverse, for example, is becoming hot, so they roll out a project, and everybody's anonymous, and piles of money flood in, and then the promoters do a rug pull.
You don't want to be caught up in all that nonsense.
I don't say that to discourage you.
I say that to open your eyes to the fact that scams can and do occur in the crypto space.
There are many ways to protect yourself, and one of the best is to go with tried and proven projects.
But yes, crypto can make you rich fairly quickly because 10x, 100x is not uncommon.
Just look at any typical five-year chart of Ethereum or Bitcoin to see the massive gains to be had.
If you have a high appetite for risk, look at the projects of DeFi and Layer 1.
They would blow your socks off.
