Yes, agree with you all. coinmarket can really help to find the coins best performing. But in most cases this is already to "late", at least for pre investment.

What about coins, that are getting hot e.g. for a specific day. Like for example a coin that is highly discussed on twitter and through that, creates the market need.
So you would need a system, to know, before the market, what is "hot".

Is something like that available?
