What do they do as a hobby that keeps them focused on their task?
Do they see movies while trading and waiting for an outcome or do something else during the time?
You can have work and be a trader. You can open a position in the morning and later check after work in the evening. If a trader is not working, he can prefer to check the market price of the coin he used to open a position, checking the price often but that is not good as it demand energy than traders will think until they notice that it is exhausting them. A trader can be the CEO or manager of a company. A trader can be anyone and he or she may have work. Depending only on trading is even not advisable.
I wont advice someone who is a trader to be working on site unless he is a freelancer. Only that way he can be able to manage both work together. It is good you are doing something online relating to trading so that you can be checking your trades regularly to avoid missing the time to exit trade or enter a trade. Although there is this setup or configuration that when the trade reaches your target something about stop loss and take profit it will automatically execute the command. However it still wont foster concentration. I just feel like a trader shouldn't be distracted.
