I'm a newbie and have been into crypto for a couple of months now. I must say the advice from other members about not checking trades too often is very good. One can become obsessed with it, and I think the thrill of the "win" can be quite addictive. Similarly that depressed feeling when the world is "red" can be deflating as well. There must be a "happy" medium, if one is to maintain a balanced life.
That is true only if you are an ordinary hodler. But if you are a trader you don't worry if whether the market is going up or down, you are making money on every and each move of the crypto. That's the beauty of trading. But on the other side there are not so many successful traders who can accurately predict the moves of the market. Personally I try to diversify between trading and hodling))
Most people can't successfully day trade, its basically gambling and should be treated as such. I know some people can do it but they have large funds and usually have insider information.
Crypto and technology in general can be very addicting. I always make sure to set 1-2 days out from my week to go outside and enjoy nature. On those off days I try to limit my computer usage and give my mind a break. Crypto world can be both depressing and exciting at the same time.
