I know what you mean, buddy. In my opinion it is not necessary to sit to wait for the sea weather. Just see what happens to the coin. Look at the road map, the news background, ask the developers what they are planning in the near future.
Developers never tell the inside info of their work to people are trading. You think it would be so easy to gather info other that what is already known? If you are a close relative of some developer though then you might be able to get those info but still administration of such projects are generally very strict and allow very little information to leak out.
So you will understand whether to keep it or to sell at a small loss and go to a more interesting coin. The main thing is not to sell the whole cutlet. Use a maximum of 20% of the Deposit, and better than 15% So you will be able to diversify the risk and slowly accumulate capital.
I like you style, but let me remind you that not every coin is for mid-term sell. Some of them are for long term and some for short term. You will understand this classification if you enter the market and trade yourself.
