The thing is, those Subscribers or views aren't worth much anyways despite being real. The retention is going to be bad and the subs are going to be cold meaning that others just use a throwaway Youtube account.
For this, I can get it cheaper elsewhere.
Despite you being here over a year, you also haven't logged on for an entire year leading me to believe you're probably a bought account.
Even your signature AlextheBitcoiner isn't written in Italic as it was in all the others.
Over a year, yet still a Jr.
Good catch, a little bit of investigation indicates that this is almost definitely a bought account, there is no log in for over a year with no explanation, and the writing style is completely off. If there's a need to buy an account to promote you service, it gives the feeling that the service isn't very good in the first place.
What somekindabitcoin is saying about the retention is also correct. I have experience on using traffic exchange sites like the ones you have mentioned, and people will just use accounts that are obviously fake or throwaways. There's going to be a very low percentage of people who are actually going to view your video, get interested, and subscribe for more out of genuine interest. At this point, you can get bots to inflate your likes/views/subscribers at a fraction of the price you are offering.
