Still a newb myself. First crypto purchase back in June, but reading a lot and posting here for two reasons: get feedback and as a record to review past trades/setups. I have no idea as to when or even if it will pump. Nothing is certain in this crypto space. As for target, I looked for past horizontal resistance zones. Notable recent ones are around 2100 and near the ATH around 4000. There is no single right answer as far as planning targets, but I'll probably set sells to take some profit around 2100, hope for some sells around 4000, and keep some of the bag in case it goes higher.
As for targets, if you use the ichimoku indicator system, that can give you some ideas for areas of resistance that can serve as good areas to take partial profits. Sometimes just looking at the chart with all indicators turned off lets you get the clearest pictures of resistance zones to watch for.
