End of June and beginning of July is considered as Bank Year. Last day of June is the end of the Bank year and first day of July is probably a bank holiday. I think this is the reason for the recent drop and jump back to where it was. This doesn't look like a trap to me but it certainly doesn't prove anything that this might be the time for a crypto comeback.
Yes, this a good sign hopefully it will now a continue bull run. Although it is still not a sure run but at least it is started to go up. Sometimes there is also some big investors try to manipulate the market status.
