Investing should never be mandatory and should only be done with funds you can afford to lose. Especially for highly volatile and risky assets like cryptocurrencies. So I don't think it's a good idea to focus on a monthly plan if the amounts invested are substantial. People doing that should do it as a game of chance, without specific goals. If they win, they must be happy, but if they lose, it shouldn't affect them, they shouldn't have to care about it.
yep which is why its advisable to have savings first.. to have the easy access rescue pot you dont want to lose to stupid gamble decisions*. as the safety barrier.. to cover the events where money is needed
investments is then the secondary event which to use excess funds, you are less emotional about due to having the savings rescue pot.
you are then less likely to panic when it comes to investments*..
the mindset is if the money you dont spend which you want to invest would have just been spent on frivolous stuff thus a loss anyway, you might as well aim it at investing to potentially increase wealth, still in the knowledge you might also have made bad judgements by spending it before. thus less emotionally attached.
i personally think of excess funds as:
money IF used for a luxury car just to show off for others benefit that still ends up turning to rust, just like an inexpensive car does..
money IF used for luxury food.. it would have become a toilet flush the next day, just like home cooked food,
money IF used for luxury homes require higher ongoing maintenance, landscaping, heating, bills, taxes, .. a cosy home is better
so living within your means can keep you from over-extending yourself and avoid incidents and money troubles.
thus i dont panic when investments yo-yo short-mid term. i dont need to touch it short-mid term. because if any real world incidents happen i have the easy access savings to cover that. so i am more free to then invest without the risks/fears.
..
when people decide to go full-anal frugal and live like a hermit crap, delaying living comfortably within means and instead surviving below comfort, below basic means.. they then get emotionally attached to the investments and more likely to make mistakes short-mid term*
*mistakes like still FOMO buying near new ATH, mistakenly thinking the price will "to the moon" forever and never come down
be cautious with your money but not emotional to the point of making mistakes due to excessive greed overtaking rationality, or panic causing you to sell at a loss
