I also didn't heard about this coins and i never invest on them, i think the best bet was either choose top altcoins or just hold the bitcoin because is the best bet you can.
The fact is that here Altcoins are very much focused on the weight of the cryptocurrency market. If the market shows a positive upward trend, top-top altcoins also go up. But if you take into account other coins, they can also display in their price the degree of their development, as well as the degree of public interest in this project.
If we compare foreign activity and activity on the cryptocurrency market in the past years, then it seems to me that things are very bad. But I users of cryptocurrency in general temporarily out of the market, but at the same time left only rating assets. Everyone is waiting for the recovery of the cryptocurrency market and even expect to see what will happen.
only those who have lost everything and do not believe in the real establishment of a cryptocurrency market have left. Although I very much doubt that all users of cryptocurrency who invested in their funds at the end of 2017 left the market. They have no reason to leave, I will not return to what they spent in due time.
