Where OP's mistake lies in not choosing Bitcoin. If I'm wrong about what the OP meant, I'd say that he didn't explain what coins he was losing money on.
Long term investments have more benefits than short term investments. I don't recommend people to trade on Bitcoin, but I rather recommend people to invest in Bitcoin.
Long-term investors can make any decision according to their wishes. But waiting until it reaches the highest price is a good decision for long-term holders. Different from those who choose short term.
More beginners like Op, don't know much about how to trade with strategies or even if they want to invest long term, they still need direction in choosing assets and important warnings not to panic when in the short term something happens that is not in accordance with the investment plan.
but if within 1 year he loses his money in the trading process, he should have learned a lesson. When losses continue to be experienced, it means that there is something wrong with his understanding of trading.
Everyone's interests will be different. There are those who prefer long-term investments and there are also those who prefer trading. At least for a beginner who wants to start, he must have someone who can provide explanations and knowledge to him.
Without knowledge and direction from people who already have experience in the investment field, it is better for us not to try to do it because it will cause us losses in investing and if we have the desire to invest, I think we need to seek knowledge about investment from those who have have experience in this field. You are right, there are two things that can be done in investing, some do it long term or short term, but in my opinion, if we just try it, it would be better if we just try one of them so that it can be easily understood after understanding it, then we will You can try other ways to get profit.
