To be honest, I regret a lot about my short term strategy.
I sold too many good coins which should have given me good profit already.
Well its up to you, but for me if i were you, i will do both, if i dont have enough time to pay attention or do day trading then i will prefer to long term. Because in day trading time is the moat important. You need to pay attention always because price changes for me time to time. But for now i prefer long term especially on bitcoin.
