Maybe you need to try it first. In my opinion, if I have a big capital, then I would choose to invest short term in bitcoin or altcoin. If I only have a small capital, better sayq invested in the long term. But one thing is clear, traders who choose to trade on a short-term basis must have a high degree of accuracy of analytical accuracy. In addition, short-term trading should often find out information about the price of the coin.
Actually to choose which one is better, whether to use short-term trading or long-term trading, depending on you who will undergo trading. Each person's trading style is different so the needs of his strategy are different. In addition, capital also determines our trading style, whether short term investment or long term investment.
