It is upto you that what type of investment you wanted to go like short term or long term, their are altcoin which are good for trading for short and long time, but not for day trader. some are like ICN, GNT AND VSL this are some coins which i am trading for last some months and are giving me around 20 to 30% on each trading. Other then that in long term also they are good.

Other investment which are offering of giving you high returns i dont believe them as they dont have full proof
investment plan and they are mostly scam. So for me where i get 10 to 20% return is good and trading is much better for me as i am controlling my investment so risk is mine and i cannot blame others for it.
