I agree that with the fluctuations of btc market then short-term investment is more reasonable and as you say, it is also more risky. But I believe that long-term investment is still a good profit for us. If compared to the previous time, btc prices have increased a lot and that is the opportunity for investment ,both long-term and short-term.
As you say, btc trading is just like stock trading. So the basic principle is to buy at low price and sell at higher price. You have to understand that choosing the right time is the most important part of your success.
