Why is bitcoin necessary? The question is how to increase money in principle. Perhaps I would allocate part of the money for trading. But basically I would think how to save and only then how to increase.
Why bitcoin necessary? well we are in bitcoin forum though , that's why the Op asked to our insight on how do we increase our bitcoin value.
For example, you can buy real estate. You can also put money at a percentage. I know that at StormGain they give 10% per year.
There is always a risk just like any other thing, from estate there are some cons that I know about it that makes me too cautious on that stuff. Let's say bitcoin and real estate in comparison, in terms of emergency you cannot just liquidate the property which means you need an exact amount of time before converting it into cash unlike bitcoin. Aside from that real estate is increasing in liability when something bad happens on the property. Have double thoughts about it.
