Trust is important in crypto investment, and as investors we must have an optimistic attitude and self-confidence, always be able to control our emotions when market conditions deteriorate and the influence of prices is not stable.
Its good to be positive about the things you do, investing is one of them. What makes someone good investors is hard to say, some are just lucky, others even with hard work dont make anything good. As investors I think we always need to have balance, between our money, investments, longterm or shortterm, we need to know when to get in and when to get out, when to invest more if situation demands. Being good investor means that you are ready for the changes and to have some plans ready when they come, whether they are good or bad.
