Saving money on a long-term period of time has several ways, but if you are asking how to have savings here in Bitcoin or crypto world for what I did actually, every time there is a profit I received whether it is from trading or bounty campaigns I automatic segregate the 15% on my earnings then place and keep it on my offline wallet like hardware wallet or cold wallet then hold it in a long term.
I had also do that method but i end up spending my savings because of some emergency cases that arise.But i still want to save again for my future because there is no assurance that your body will always be fit, and you can't work anymore too because of the old age already.
Thats true, you also have to think about your future later dude, try to set aside always a few percent of the income you get each week in cold storage to store up to the future so that your future can be guaranteed, I also do that at least take 30% of my income for stored long term..
