As saving is generally considered a long period time, you should invest in a place that can give you good returns over a long period of time. If someone is saving fiat money then at some point he may lose his money due to inflation. And if someone keeps buying gold it also increases in price but comparatively much less than Bitcoin. That's why I recommend saving in Bitcoin to those who want advice to get good returns. As you can get high returns on investing in Bitcoin. Also you may have to wait for a long time. Bitcoin investment is perfect for those who plan for long-term.
