$ETH Prices fluctuate up and down, sometimes completely without warning. But when one learns to read the market, follow important news, and have a strategy, they can gain something from it. It's important not to panic, use stop-loss orders, and not be afraid to realize profits. Those who have bet on Bitcoin or Ethereum in the long term have generally not regretted it. And those who are not afraid to speculate can catch interesting opportunities, for example in altcoins. The key to success is to have patience and not to be guided solely by emotions.
