I will begin by answering the obvious and clear question, of course, your community and what the more echo of it they make, the more popular they will become and the characteristics they may have are, how is that? Well, each cryptocurrency, let's say they have a different style and method, although some are very similar, it should be mentioned.
What is certain is that it depends on the use that you give to the cryptocurrency, it will make it more or less popular, for example:
-The famous Bitcoin is one of the most recognized cryptocurrencies, especially because it was a pioneer, at that time its value was not as high as it is today, the goal of its creator (Satoshi Nakamoto) was to design the safest medium digital transactions and private, that is also free of a regulatory body (this is the basic principle of use) that works with a chain of blocks, that is, a distributed and secure database, that is in charge of verifying the transactions of the users, then its value is given by a law of supply and demand; With the success of Bitcoin, more and more cryptocurrencies emerged that have different concepts and uses.
-Litecoin, has many similarities with the aforementioned cryptocurrency, because technically they are very similar. However, Litecoin's block network is much faster than the previous one, since it only needs 2 and a half minutes to complete a transaction, while in the other it is 10 minutes
-Dash, is an open source cryptocurrency that uses a P2P (Peer-to-Peer) system that offers instant and anonymous transactions, one of the things for which it became famous, was the introduction of anonymity. Remember that cryptocurrencies usually offer privacy because user data is not known, but everyone can see them.
-Pivx, is a cryptocurrency that focuses on verified private transactions and instantaneously (hence the name PIVX) could be said to have everything that characterizes the other cryptocurrencies; its design is focused on correcting the deficiencies of the others.
To conclude, in my humble opinion, I think that every cryptocurrency is incredible but its creation was basically elaborated to be free of any entity and we can already deduce that we want privacy in every aspect, so I bet everything to PIVX, it is that there's nothing better than having everything in one, sounds trite but it's like that
