How much time do you think is left to buy Bitcoin before not owning any leads to demise, detriment, or worse, poverty/financial slavery?
The effect of not owning Bitcoin is not that detrimental to the extent that it will mean a direct implication of the demise of those that don't hold it or automatically means that they will all become poor or financially enslaved. Even though for those that knows of the worth of Bitcoin, it's necessary to get invested in it, poverty is a function of somany other variables and not dependent on ones inability to investing in a single digital asset.
If you're not investing in Bitcoin but you're investing in other real assets and you're going about them the right way, they will inevitably take you out of poverty. The best time to invest in Bitcoin is definitely now and any other time you've got the resource that will keep you invested. Procrastinating will only lead you to buying at a more expensive rate but yet, that doesn't mean that buying Bitcoin in the next couple of years to come will be totally impossible. Give it four to ten years time, a lot of newbies will continue to join the ecosystem and will start to buy Bitcoin at whatever price they meet it at.
