SanDeGo is a POS CryptoCurrency which is based on BlackCoin.
SanDeGo has a lot of coins which will be issued and the POS interest rate is high. Therefore we can do tip easily.
We plan to add tipping functionality to social media sites such as Twitter, Discord, and other similar sites as a method of utilizing this coin.
We also plan to develop a web application as an original platform for the purpose of sharing knowledge and wisdom in exchange for coins.
By using the app a requester can send the person who responds coins in return for their advice.

Out of the Pre-mined 10 billion coins, 4 billion is for AIRDROP and 1 billion is reward to collaborators.
2 billion will be sold at a special price which is 1 satoshi per 1 SDGO after the coin is listed on an Exchange and remaining 3 billion will be burn.(Coin numbers to be sold by listed sale was changed from 5 billion to 2 billion at 19th/Jun/2018.)
SDGO coins remaining after AIRDROP and the limited time introductory sale at a special price, all remaining coins will be burned except for 200,000,000 SDGO for reward.
In addition, the reward is locked up except in the case of being withdrawn to pay collaborators.
Therefore there is no possibility that the insiders of SanDeGo sell out SDGO unfairly on exchanges after the special sale price of 1 coin per 1 satoshi.
