I'm with you mate, it's better to ride in for short term and ride out when you've make few good gains, I'm not into crypto investment for long term, I will always jump from one project to another, once I made good gains from a coin I will find another
If you are looking for short term investment or trading then Deflationary Tokens are a good choice for that purpose. You can take short term position with them as they are very much volatile. BOOM is doing good on exchanges, you can try that.
