Don't invest in anything, any crypto currrency if you don't accept risks at whatever levels at the beginning. Investment is a game, basically, with two sides: risks and opportunities. Sometimes, investors can take risks and get good returns back; but sometimes they take risks and get losses back. That's life and that's investment game. There is nothing, and no one can guarentee 100% that you will not get loss, and only get good returns with your investments.
