Alts price bouncing back or should we sell?

After watching the whole market drop i thought i was lucky to get some alts almost at the bottom of the dip but almost 24 hours later is making me wonder what's going to happen next. The market seems pretty quiet, while the alts i bought, while i am still in profit, they're just bouncing back to the price i bought them. I wonder if i should just sell for profit now or just hold and hope alts will bounce back once BTC halving happens. I am kinda new to this stuff, so please, bare in mind, while i been a couple years around this world i still lack some knowledge. Thanks in advance!
