I think short term trade help you to earn profit early but you have need a huge investment and take risk as well.I think long term trade can give us a huge profit but we have to be patient for sure.I think long term you can choose Eth,Aion,CS,CRD,NEO,XLM.Those coin are so stable and has a good platform to make their future bright .
