There is such a coin called Phoneum - PHT, it is based on the tron blockchain and is mined in games for the phone. There is also an application that allows you to invest the collected coins at 12% per annum. Recently, a small development team has been actively working on the development of their project. Many do not even know about this coin, since the developers do not have time for advertising, they are busy developing and improving applications.
Over the last year of development, PHT has been listed on several exchanges, such as PROBIT, P2PB2B, there are also small exchanges that few people know about. More recently, PHT has a younger brother, PHTG, which is listed on the P2PB2B exchange.
The number of PHTs is limited to 5,000,000,000 coins. Its cost is still very low and at the time of this writing is only $ 0.0001606.
This is the second year I have been watching this coin and I must admit that the developers really try and put a lot of effort into their small but strong project. Looking at how the developers are trying and how much time and effort they invest, I will not be happy if one day this project enters the top among other crypto currencies. Even though their team is small, the support works great. I applied several times, and they didn’t answer me with stereotyped phrases, as is customary, but really helped me figure out the situation. Even when I decided to write the words of support, I received a response from the support.
Of course, if the developers create a huge project that can very quickly bring them to the leading positions, it will be great, but due to the fact that their team is small, this will not happen in the near future.
Those who want to get acquainted with their site and what they are doing, go to the site and take a look (the link is not a referral, I just want to help the developers): https://phoneum.io/
