Huge difference, let me explain.

First of all when you purchase a fiver gig, you are paying for usually one account holder or a holder of several accounts to make a tweet on your behalf to his followers. You can ask the seller to provide you with the usernames of his accounts and then go to a public metrics site like http://www.twitteraudit.com and check his follower count to know his reach and know how legitimate his followers are, in most cases you will see that the followers are mostly fake, bought off of another fiver gig selling mass created accounts. This has been one of the best and easiest way for so many fiver sellers to make quick money off of unsuspecting buyers who are just getting their messages out to a bunch of bot accounts that are not even owned by individual people.  There is no way that those fiver gigs compare to what the Viral platform provides to sponsors at all.

As you can read in the op here, the exposure you can expect from having your message travel across the network and currently reach over 50,000 twitter users who are interested in crypto currency related updates. On top of that you also have the benefits of relevance related to your message and that is important when it comes to SEO, instead of having your message on accounts that are into completely unrelated interest scopes.

There is no other way currently in the crypto currency scene to gain this incredible exposure, with the flick of a switch you now have a major portion of the community who is interested in crypto, reading about you and what you have to offer. The math is simple and the end result is incredible reach with minimal effort!
