I may sound traditional but this is for me the most effective way. First, you need to have several sources of income. If you do not have it, do something because you cannot save something if you are always short of it. Second, avoid unnecessary spending. Instead, invest them on fast-growing investments such as cryptocurrency. This is the third tip. But always be careful to avoid coins that are not yet proven fundamentally solid. Fourth, if you wish to be safer, diversify your investment and portfolio.
