To achieve profits, you can heed the advice from @jaberwock mentioned earlier. Acquiring knowledge beforehand, conducting research, and embracing trial and error would be more advantageous than impulsively purchasing assets without applying common sense.
You still won’t be able to find the bottom, even experienced traders will not be able to answer the question now, have we already reached the bottom, or are we still to do it, are we already in a bull market, or is this a continuation of the bear market? The question seems to be not difficult, but you can see how difficult it is to answer it. ) Probably if you buy now, you will profit, but you can also wait and if the price drops lower, then you can get even more profit, that's all the difference.
