Patience is highly practicable in this strategy, holding from the bear market to the bull season would turned out profitable only when one chooses the good projects to invest in.
You could also say luck is needed more than patience when it come to investing in altcoins. Holding them doesn't guarantee you will be success as you will never know which one is going to survive the bear market. But when you're lucky you could guess the next coin to rise. 2023 has come with AI making the noise, nobody who has predicated that but those who are lucky to buy AI coins are now making profits.
Patience is needed for holding as without it you'll sell early and so is luck, when this two work together you'll be receiving profits from any investment that you get into because they'll do better than others but this isn't guarantee only just assumptions.
