Sell or hold

Currently holding 700ish shares of TQQQ at an average cost of $44. Should I just cut my losses now and buy TQQQ when it dips more or should I just hold?

Update: I've decided to cut my losses and sell everything. Ive bought SQQQ in the meantime to hopefully make some money on the downturn. Once things seem to turn around im going right back to TQQQ
