I've Got It
I don't think it was every easy, but I think of subscriber growth as almost exponential. Someone in one of the other threads likened to rolling a snowball. At first it's impossible to pick up a lot of mass, but then it start compiling.Yes the first 100 are the hardest. But the next 900 isn't becoming easypeasy at all....
The second one hundred is a little easier than the first. The next one hundred is a little easier and so on.
But yes. Youtube is competitive. There are huge numbers of channels, and even if you have talent and a specialized niche you are likely going up against people who are just as talented (if not more than) you and have likely been doing it longer than you. It takes work, luck, and talent (I think in that order) to build, grow, and maintain any channel.

. So it's the 'chicken or the egg'-situation
