Not only doe it use smart contracts, Populous also utilizes XBRL data as well pegged tokens in order to create a one-of-a-kind trading environment for both the investors and the invoice sellers when they trade a large number of different invoices from all parts of the world using its blockchain technology.

Data has always held such a significant role when it comes to making a financial decision.

Explanations:

IOTA (MIOTA) is the altcoin of the first group in which I was with many doubts at the time of putting together this list.
Although it is still in the beta phase I have been following it from the beginning and those who are aware of this currency know the number of problems it had and seriousness:

A) Ternary number system
B) do not follow the best cryptographic practices
C) The team performs bad practices for the open source community
D) The IOTA blockchain lacks rigor in its integrity guarantees
E) A remarkable and very bad communication of the team made the outside.

Hopefully these problems will be solved like many others.
I left it in the group because it is a very novel project, because of the interest it aroused in the people, the marketing and the machinery that is behind it, being the 11th position of the market cap and everything can be improved and corrected.

Cardano ADA (ADA): Although I did not include it. I am sure that this coin will talk but very long term. Between 2 years to 3. But highly recommended to buy it now and go megalong.

While it gave me joys I will not add BCH, for a matter of principle.
I must emphasize that I also like: Golem, Salt, Dgb, Bts, Doge, Ardor, Bat, Nebulas, Power Ledger, Reddcoin.

Altcoins that never fail: Game, LBC, Nxt.
