Trading is a very risky part while investing is you're always is a safe zone. Why? Because you can hold it depend on how long the time frame you want and the profit you have been targeted on it.
Not necessarily. You being in the sort of "safe zone" completely depends on what you're actually investing in. I mean, you could hold certain penny stocks for god knows how long and you could still end up in a huge loss.
Indeed look at some popular Fiat currencies and stocks like the dow jones and USD they're all in risk for a default due to an incoming economic default from the cause of financial crisis. Even with stable assets like this can turn into zeroes, how much more investing with something is unpopular. The reality is that there are no safe havens and only invest or trade what you can afford to lose.
