Therefore, I believe delaying investing in Bitcoin until we have discretionary funds is a bad idea. Time is ticking and can't be undone. Rather than training our mentality first, it's better to just start investing. I emphasize again that this mentality will naturally develop once we start investing, and a naturally formed mentality is better. Because, the real test lies in real-world situations.
your going to mislead newbies with this your statement above, because bitcoin investment is suppose to be done within your Discretionary income and not outside your Discretionary income, if you invest in bitcoin with money meant for settling your basic needs and expenses, buddy you will end up selling off your bitcoin investment at early stage of accumulation and in lost in other to attend to basic needs and expenses, so you have to figure out if you have you discretionary income first, because from your discretionary income you will invest in bitcoin and also from your discretionary income you will build up your emergency fund and backup fund to avoid dipping hand into your bitcoin investment to settle emergencies when they arises, sine there be emergency fund and backup fund to handle those emergencies.
