Very short-term crypto-currency investing is called Scalping. It is the process of making multiple trades in a single day, taking advantage of small price fluctuations. Scalping is also sometimes called “churning and burning”.
Some traders prefer to trade on a very short-term basis, trying to make profits from the small price swings that occur throughout the day. This is a very short-term investment that requires you to be actively in front of your screens every day in order to be profitable.
It is also a very difficult trading method and requires a lot of experience to be successful.
Scalping requires a lot of technical knowledge about the markets and assets you are interested in.
Because crypto-currencies fluctuate so quickly, this style of trading is not always appropriate for the crypto-currency markets.
