It depends what coin/asset i trade. In BTC it's long hodling and selling on big pumps. On alts it's mid/ short because pumps are much often.
I believe that at this point you should only invest in the short term, you can see that the market is fluctuating continuously and very hard to guess, bitcoin prices are constantly adjusting and rising in the days near the line but the price of altcoin is very strong. Therefore, I believe that you should only invest in the short term to reduce the risk.
