The simplest answer is it's more likely you are trading here, where you buy low, and sell it high so you can make profits.
This is easy to say but difficult to execute, a lot of investors or traders already lost a lot of money. So it is still not guaranteed, bull market or bear market, it's still risky.
That's true people often think that it is as easy as words describes but in reality it is something more complicated because buying and selling cannot only provide you profit but a better and worthy coin will identify about your profit.
I think traders faces more difficulties and more losses than investors and the main cause of investor's loss is that they sometimes hold useless coin which ends by giving them nothing in return. Market always remains risky but expert people utilize their knowledge in order to reduce their losses otherwise market is quickly changing in a matter of seconds.
