Of course in the bank you only get 1%+ every year but in the crypto world you can get more than 500%+ within months or a year.
But don't forget that bank interest is way too less risky when compared to altcoin interest , yes 500% is possible but even loosing everything is highly possible.
Success and failure both are part of life. Even in regular currency there is a high risk of losing everything. So this point is not much to be highlighted because it involves luck factor and the way how wisely you invest your money. And bitcoin is on its way to replace the regular currencies so no worries about losing.
