There is a good practice of trying to save/invest around 10% or perhaps even more for the future, yet there are so many folks who have fallen out of such a habit since for 15 years or more interest rates for savings accounts have continued to come down, and there have frequently been dynamics worse in some countries as compared with other countries in which currencies don't hold value so there are incentives to spend it - especially since there is no place to put it, especially if we are talking about only around 10% or so of the income..
Let me start with bitcoin has provided solutions to so many problems seriously in the past there is this dilemma of where should one put his savings into, 10% is very little to start a business with and even if there is substantial amount for that, the problem of having time to run that business is also there. Then aside business people then think of which asset to put the money into and if in the future the asset will grow in value. After some of these analysis most people simply go for the idea of saving in their local currencies and at the end of the day inflation eat it’s up.
With bitcoin there is no looking for any currency that will face inflation or any asset that has potential. With bitcoin you don’t even have to start thinking of how to run the business, you simply just securely hold it for as long as yiy want, but yet newbies are still doubtful. For me I think the biggest hurdle around been profitable in bitcoin is actually making sacrifices and this is squeezing out savings to put into it and holding for long
