First we need to always knowledgable and have a continues learning to become motivated.
Being knowledgeable about bitcoin is easier and more simpler than going for altcoins which done reveal what they are doing and dont have enough of a marketplace to sell their service. In other terms those which do not have a sustainable market of their own are easy to detect and not invest in.
And last one is avoid too much greed because it will drives you going to loss.
I think greed has an importance but the more important thing is the FOMO. People need to stop getting FOMO over some coins. Do not buy at the all time high. If you feel a certain coin is worth putting money in watch it for when it does go down and not go up, because once its up it will be dumped hard.
Watch them like a hunter preys its food. Pounce on them when they are weak. even though it doesn't guarantee you anything even you are knowledgeable at least that is better as the starter.
experience is everything in this trading business and to gain the experience -as everything has a beginning before it turns experienced- just do it ! execute more important rather than thinking too much , sometimes it even makes you stepping back doing it.
you can learn more when things has been running, don't scared to fail.
i learned a lot from the mistakes that i made in trading and it makes the better version of me after that.
the real learning is through experience, even if you bought it on the all time high which it is really a big mistake but in the next days , next time you will become a better trader as you have gained experience.
