Too many people get caught up in the hype of investing without first building the financial foundation to support it.
Talking about this your statement here, I don't necessarily think that you must be solid financially before you can start investing in Bitcoin, once you have a discretionary income that will enable you to invest in Bitcoin consistently, you are good to go, along the line you can be working on your finances to make it more stable and reliable, but waiting to build a solid foundation financially first before starting is another way to delay your Bitcoin investment journey.
Investing should come from a place of surplus, not pressure.
Yes, you are actually right here, investment in Bitcoin should only be done with our discretionary income, which is Money left after all our basic needs have been met, so that we will not be in any kind of pressure financially, so you are actually right here.
