It may help to some extent but believe me if you have a big FUD brigade form influential whales that wall can come crashing down in seconds. There is too much corruption and market manipulation in crypto currency trading and icos so prepare for that wall to be smashed by ruthless parties before you see your coin mooning or even attempting a lift off. I have really seen the worst of people's characters come out when it comes to crypto, I mean really gangster cut throat stuff. SORRY If what I said has burst your bubble, I say that from direct experience of launching a coin myself a few years back.
Why would the whales crash the wall, what's the purpose and how can they make money of it ? It means that they would sell their coins to me at the lowest price of the market (because the wall would be the bottom line of the buy orders, no one would put a buy under this value because it would mean that the market would completly crash). it really don't understant where is the interest of doing such things, even in terms of money !
