Nice amount of subscribers actually. I guess this channel can be developed by someone else in case someone who will buy it won't be a slacker. To my mind, you have to be vigilant enough in order not to face scammers. There are plenty of such ones in the internet and they can easily cheat on you. I believe that youtube nowadays is a very profitable platform where you can earn good money. However, there are also other platforms where people are able to earn money, for example various freelance platforms. If you have decided to sell your channel then you will have to convince a buyer that the amount of subscribers on your channel isn't fake.
