You can look into
www.thechampcoin.comIt's become very famous in India and compared to any other altcoins, TCC has gained more amount of users just within 3 months or it's release which would be around 5-7 million users already + the prices since its release has gone up by 30 times.
In its Early stages it had few issues but the system has been update and it is currently a 4 step unbreakable system.
Mining here is done by adding 9% coins on your wallet balance very 6 months(1st of June and 1st of Jan) and will go on for 5 years.
Current amount of coins released in market is 200 million and 300 million more coins will be released in next 5 years thru mining. Most of the information is on their official webpage given above
My personal experience - In Jan I invested 3.4 bitcoins on TCC and now my return is 76.083 bitcoins.
The only issue is the system hasn't yet released the built in trading function, so buying or selling thru system is not possible.
At present situation one can contact a TCC agent and purchase from them then hold the purchased amount in TCC wallet until trading system is online or can sell those coins to other purchaser at a higher price.
Good new is the trading system is already being tested rapidly and will be released within this month
The bad news is when trading system releases prices will be hiked for coins
If u get interested then let me warm you to purchase TCC from people who u know or trust bcaz there has been many cases of people sending BTC or Money to sellers and not receiving TCC in wallets.this happened to me few times with other altcoins.
For detailed information you can always contact me on whatsapp at +918586858640, I will provide all official proofs of its existence and acceptence.
My opinion it's trust worthy, secured and has a bright future ahead in the coming few years.
