First rule of the game, don’t be too greedy. Second rule of the game, don't be too much in a haste to sell if you know what you are doing. If a crash is imminent, and you can read the charts, then you do not have to sell now and watch closely for that moment in case the bull run continues, otherwise, you have made some good profit now, so you are still good even if you sell and it keeps running still. If you trust the project, and you want to hold for the long run anyway, why bother? If your plan was not to hold for long, and you do not have any selling strategy, you can sell now. It is going to be a long run for IOTA, but no one knows how long it would keep running before a correction happens.
When the price really satisfy that i think when i will seel that it is a big income for me. That when i estimate it i will gain more income if i sell it that time. But who know that the price is going down or rising up. You only know how to sell. No one can prdict the price soon. Ut you can have patience to wait and to seek higher income.
