Sure.. not guaranteed.. but it surely seems like a good thing to do and a good place to put some (if not all) of your extra value that you are willing to invest.
That's true, there's no guarantees that Bitcoin price will just continue to keep increasing, but still investing in it worth the risk . Because it has already proven to be among the best investment, that any one can easily take part on .
Fait is getting inflated everyday and value keep track with higher amount, I won't suggest we keep or save in Bitcoin, it a very volatile asset of which we cannot be too optimistic of increasing value rather we invest a certain amount which we can afford to lose. You can expect someone to save in Bitcoin, the money that would have been used for daily needs and other projects, what about bear seasons or price corrections this cannot be overstressed we all are optimistic yeah but there should be limit, you can only do that when you have more than enough money at your disposable, if that's not the case it cannot be seen as Investment but financial illiteracy.
With such mindset, the chances of you accumulating some good Bitcoin Stash is low . Like for instance someone is being paid monthly $100 and $50 can cover his expenses. And he has like extra $50 he can use for anything, and Such individual decided that he wanna invest in Bitcoin, and he has the mindset of using only money he can afford to lose. And at the end $10 was the amount he could risk if he continues this way it won't be able to accumulate more quantities for himself.
The best thing to use is that before should accumulate Bitcoin he or she must have some cash that will serve as emergency funds while they accumulate , like instance being paid $100 and $50 can serve as emergency funds. He or she can use $30 as his weekly purchase fir Bitcoin accumulation, while he hold the remaining amount as reserve funds.
