In the light of recent events, the question became urgent: How to understand that your position on crypto-currencies suffers because of market fluctuations, and not because of the whims of speculators?
It's very simple, but some ignore the simplicity of this advice.

Open the capitalization of the Crypto-currency. This is a good metric for understanding where the market as a whole is. Next, move to your crypto-currencies.
Having seen the place of the crypto currency that you are interested in in the general rating and evaluating its neighbors, you will receive very important information about the effectiveness of your crypto currency in competition with others. This information will allow you to draw conclusions about the current situation of your position. If the coin began to lose its place in the global capitalization rating – perhaps, this coin is influenced by fundamental factors or a speculative element. If the crypto currency keeps its positions in the rating, while losing in the price - do not worry, maybe this is only a global market fall.
