In my opinion Subscribe for Subscribe is pretty much useless. After doing it a while ago I began to regret it. Subscribers doesn't really mean anything.



What Real Subscribers Do-
Good Effects-
They tell they're friends, other friends tell they're friends, etc.
They always watch you!
They will like the video if they like it.

Bad Effects-
They will unsubscribe from you and won't watch you anymore. ( I doubt this)




What Fake Subscribers Do (Sub4Sub)-
Good Effects-
They either stay subscribed and don't even care of you're channel.
You could gain a fan ( 20/100%)

Bad Effects-
They unsubscribe from you because they don't want anyone too see that they did sub4sub.
This won't even look legit.
-> Ex: 1000000 subscribers, 50000 views. (WTF?)
You won't gain any respect.



Watch how you do sub4sub. Will you gain anymore viewers? Will you gain more money ( if you're partnered). I doubt it. In my reality I have done sub4sub and I regret it. I didn't gain anything from it expect fake subscribers which ruins my channel. It won't affect you but this will affect you're channel. You may think too you're self " I feel so famous! I'm going be partnered by a network!" No wrong. You won't be famous because you have no true fans. You're not going to get partnered by a network because Networks only count on views. Not subscribers.
So Think again before you subscribe for subscribe. What I'm trying too say is DON'T DO SUBSCRIBE FOR SUBSCRIBE. ITS BAD. I can point out an actually example.

1. An actually good decent channel!
He would gets fans.
He would gets paid because his fans watch him.
He would shows good content.

2. An actually bad channel!
He would get nothing.
He would not get paid
He probably has bad content or he just wants too think hes cool.
He gets nothing expect FAKE subscribers.
