if you decided to apply those short term policies on top altcoins then it might be okey because they have top marketcap & volume, so absolutely those will be pump with good price, reasonable for longer investment. But if you want to apply those same policies on from middle to low range altcoins, then that might be uncertain cause it hard to predict those within short period. They need sometime to reach i mean long period
This depends on the target you want to achieve the profit you want. If you find it unsatisfactory you should wait for any increase you may want. so it all depends on your choice later.
