No, I totally disagree with you that mining is the only way to earn Bitcoin. You can make a significant amount of Bitcoin with the DCA strategy, which also starts with a smaller amount. It doesn't require a large amount; you can just accumulate Bitcoin with a few dollars. While mining required much more money.
 
Did you know the cost of Bitcoin mining?
 
It is quite expensive. And we also need a lot of stuff to get done.
Below are some of the components I write that are necessary for a mining plant.
GPU
Power Supply
CPU (central processing unit)
Memory
Motherboard
SSD or Hard drive
Frame
Colling
 
So these are all the components for mining. The cost of all these together is quite expensive. Apart from this, stuff like an electric bill, a separate room plus AC, etc. are required. You can also see how much money comes from mining in the below picture. So mining Bitcoin is good, but it is not for everyone to collect Bitcoin. While everyone can accumulate Bitcoin through DCA,.
