Firstly I think it's a bad mindset to invest for short period of time, if anybody ask you to invest in a coin and you will be expecting profit in a short time I think that's a lie, the best thing is to invest in a coin  for long-term. Also If you are investing in an any coin I think the best coin which you should invest is bitcoin, that's the only coin which am sure your profit is secure if you can hold for long term.
