My favorite altcoin right now is HVN.  They just secured a deal to be integrated with a major regional ERP software to service small business in Russia as well as central and eastern Europe.  They work in the factoring industry where small business sell their outstanding accounts receivable invoices at a discount in order to get immediate liquidity.  It is a 3 trillion dollar industry worldwide and the market that Have has secured the deal for is a 700 billion dollar market.  They will release a working demo on December 21st (a little more than a week from now).

Populous (PPT) is in the same industry, does not (to my understanding) have a working product yet and does not have a deal this large secured (correct me if I am wrong) and the Populous marketcap is currently over 1.5 billion dollars.  HVN's marketcap is 27 million dollars.

In my opinion, the Hive Project (HVN) should be greater than or equal to Populous and it is currently 55 times less expensive.

There are many other good coins/projects to invest in with good upside, but I am the most bullish about Hive at this time.
