I recommend reading the official Diamond theme to understand that this coin is one of the best "old" coins on the market.
I also recommend asking the questions of interest to the best development team that I know.
Almost always give competent answers and responsibly relate to the case.
I learned about Diamond (DMD) 3 years ago, when the coin was cheap and during that time my capital increased significantly.
This is an investment coin, not a shit coin.
This coin like bitcoin, but better, because the coin brings interest every day, month and you can spend it on your need. And with the sale of interest, your fixed capital does not decrease, unlike bitcoin. And all you need is to launch your wallet and receive interest and you do not need to risk trading on exchanges with other coins.
Definitely Diamond is a coin that I would recommend to friends and acquaintances.

PS: and I do not care if someone does not believe in this coin after my words, for I see that my capital has increased significantly and this is reality. My call is an opportunity for people to figure out what coin to choose for medium and long-term investments. Think, decide, increase your capital! :)
