Of course, no one should invest with non-discretionary income since that would be gambling rather than investing, and yeah, discretionary income can be increased by increasing income and/or decreasing expenses.
Yeah it would seem more like gambling if one goes beyond discretionary income but some times I do have this feeling if we are only buying bitcoin with an amount can afford to loss them doesn't that make it a gambling because we are afraid we might losses them? lossing can be in many ways but the most fear in this instance is the fear of lossing it to crash or hacks/attacks. I prefer to invest into bitcoin with an amount that I can afford but not the chunks from my discretionary income, if we keep it being only a little of what we can afford to loss to me it's now a gamble which bitcoin is not.
So does wealth preservation mean gambling?
Wherever you keep wealth, it can be destroyed. If you keep it at home, it can be stolen or burned.
If you keep it in the bank, the bank can be robbed.
In this case, can you call wealth preservation gambling?
In fact, people want to store all those assets from which they will get a good profit in the future.
People deposit money in the bank to make a profit.
They store land or gold so that it does not lose value.
People can store the assets that they are more confident in.
Now if people think that the future of Bitcoin is bright and they can get a good profit from it, then they can store it.
People now think that a good profit can be obtained from Bitcoin, so they are storing it instead of gold or anything else.
