Of course you have to be mentally stable and not to be stressed to much when doing trading because it could affect your overall result later in trading.
It's needed to be stable mentally because it's your emotion that might put you in the wrong or right trades.
I'm stumbling upon being a seasonal trader as I'm looking for a lot of cryptos that I want to invest in. Despite having the budget, there's something that stops or delays me from doing it.
It's good I think to be both, passive and seasonal. You have passive investments while actively trading.
