Trying to sell some coins with high gains to buy some that has dipped alot, but it seems they all move up and down together for the most part. This makes it hard to sell. Is this how it normally is? Been trading just a month now.
Of course not, they have different fluctuations depending on the 'large or small' number of 'users or investors' behind it. In the case of a 'mutual' decrease or increase, this is usually due to sales, and purchases occurring simultaneously on each cryptocurrency or possibly a simultaneous closing of cryptocurrency exchange accounts in a country.
