Few questions on Youtube:
1. If $10 is the min deposit, then that means I have to buy at least 1000 likes?Not only likes $10 is consumable to what ever services you want, for example you can buy 2000 Low retention views for $0.80, 100 likes for $1.2, 100 shares for $0.60, 10 comments for $3, 25 dislikes for $0.3 Total of $5.9 and you still have $4.1 left to use on other services you likes.
2. If I buy 1000 likes, can I choose what videos to split those likes into? ofcourse!

You can split it to 10, 20 on what ever you like
3. How long after the order has been processed will I receive all likes? Are they given over time? If so how long over time? 2 days I guess? It depends on the service and quantity of the order but most likely the order is done within 24hrs on some likes services.
4. How much audience retention is each like worth? A few seconds into the video?
