Guessing is the lack of information to create a liable answer.
Trading cryptocurrencies is more than that. Skills in analytics and pattern-recognition is needed. It means you've understood the flow of the charts and created a possible outcome in your mind.
If you are a good trader, I will ask you this. Have you always been profiting all the times you have been trading? If NO, then that best answers the fact that it is a guess work but you are only safer doing it with some good analytical skills. If you have always been profiting without a single loss, then I will say you are just still lucky or new and sooner or later you will understand my first fact that i stated before this one.
