OTOMAIN Token details :

Name            : OTOMAIN 
Symbol          : OTO 
Total Supply    : 250.000.000.000 OTO
Decimals        : 18 
Mainweb         : https://www.otomain.com

Total Supply  : 250.000.000.000
Total for Tokensale  : 150.000.000.000 OTO
Future development : 50.000.000.000 OTO
Team  :   25.000.000.000 OTO 
Promotion and Airdrop  :   25.000.000.000 OTO

* No Minimum contribution on OTOMAIN Tokensale
Send ETH To Contract Address you will get OTO Token directly

** Don't send ETH Directly From Exchange Like Binance , Bittrex , Okex etc or you will lose your fund !!

A Wallett Address can make more than once transaction on tokensale

You can also get OTO airdrop with send 0 ETH to contract address , you will get some OTO Token directly

Set GAS Limits 150.000 and GAS Price always check on ethgasstation.info (use Standard Gas Price or Fast Gas Price)

Unsold token will Burned
