believe in yourself and believe that everything you have done is a very appropriate decision. that is what must be embedded in sellers so that they are not always in fear. There is a saying, don't be afraid of failure, because failure is a step towards success. I strongly agree with the advice you say to record the reasons when opening a trade, maybe this will be a very valuable lesson for me, and can motivate me to be more careful in trading so that I can get the results as expected at the beginning of opening a trade.
Try and try until you suceed, there is no room for fear, you need to try all those things that might be helpful in your trading, loses in trading is normal, but a very huge one is bad. We need a lot of patience so that we could wait till our sell order hits, long term holding is very crucial and we can be emotional when waiting for our coin to pump.
try and try until you succeed? Trading cryptocurrency makes a difference on that quote, you cannot just try and try after try... it will be more right if it's try and try if you afford to lose because the market will test you until you lose your patience and money since volatility is at the very high rate especially top 10 coins in the market. A good advice for now is just to hold until the next halving, that might be a good strategy for the moment.
