twitter, yoitube, articles on the steemit, these are the best way for marketing a new crypto.. 
All these will be easily covered up through a bounty program. Yes, that is the reason almost all the new ICOs are focusing on having a large bounty program. Basically to reach more number of crypto users, signature campaign will be very effective. Because reaching more crypto users will definitely take any new project into success.My question is mainly how to do the marketing if you are launching a new crypto currency step by step ?
I believe we do not need to think big. Just having a signature and twitter campaign in this forum will be doing all the needed job in couple of simple steps. Having a manager and asking them to start these campaign will be more than enough for marketing any new crypto into this crypto community.
