keep up the good work doge

Good morning, I'm new to the cryptocurrency market and I would like to know about my portfolio, I've been reading the comments of more experienced people here and making some decisions, it's true that we have to be patient and have a strong heart, hehe, with the wave of ups/downs (whales), I have the impression that buying low and selling high (trade, right?) is a more than wise strategy, is it worth taking the risk at this moment? I'm looking to make a profit in the medium/long term, it's money that I won't need so quickly, I'm just getting excited.....
