A good trader will never get greedy and invest in coins or tokens that go up and down wildly only to get more profits because with more rewards comes greater risks, so when you are investing in an altcoin only for the quick profits, you might end up losing your capital in that investment.
A big partnership, or positive news about the project, can trigger a very good pump, so it is said that altcoins for trading can be more profitable than bitcoin. But firstly, such moments are not always easy to predict, and secondly, the altcoin price does not always react to the news with such a large increase as expected. Sometimes a pump can happen without a news background, and it seems to me very difficult to determine it initially.
