Which do you prefer?

Hello Everyone, want to ask few questions here.
Short term or Long term investment?
Which is more profitable to you?
What coins do think that is good for long term now?
Feel free to comment your ideas and opinions.
Now a days, i prefer long term investment because in this way i can have an assurance that i will be earning a huge amount of profit in the future while short term will not give you so much profit because the market price will not always pump.
