This trading strategy in crypto sounds easy, but it's not that simple. Selling coins can be done when prices are high, that's an opportunity we can take to get a profit. And no one can really predict the bull market in the crypto market.
it's just a trick that has been done since time immemorial or the first existence of a trade or digital currency, selling when rising and buying when prices go down but the main reason for all of that is our knowledge of when prices rise and when prices go down.
