Beginners tend to be easily influenced because they don't really understand the Crypto world where there are always lots of choices or management time to invest in Altcoin.
Actually it's easy if the market goes down we hold and if the market goes up we sell, it's just that we can't guess the growth of Altcoin because coin growth depends on the success of the project. You must be able to adopt coins that meet the requirements and understand the long-term or short-term potential.
