I don't want to repeat this bitter experience in 2018. in 2018 I released eth coin at that time the coin price was very cheap because I had doubts about eth coin I was afraid the coin price would go down so I released eth coin, now I am very sorry from that experience, now I don't want to be careless in selling my coins, I prefer to hold the coins long term.
indeed
"experience" is the best teacher who will always remind us not to keep repeating events that have been done. you have experienced this, now you can be wiser and not careless anymore. happy who have been able to overcome such things, because not all can and have experienced it.
holding the coin for a certain time or maybe releasing the coin, must be because it is based on an analysis that has been done correctly, so not everything that will be done can be ascertained to be the best step, because without any prior analysis it will be in vain.
for bitcoin and ethereum, obviously holding for a long time is the best way because they are investments for the long term and are different from other altcoins.
