I recommend to NOT monetize videos immediately, but rather let the channel age for a few weeks before enabling monetization and connecting it with an adsense account. Build up the channel first, make it popular, have many videos and lots of views, getting subscribers wont hurt either.
THEN, once you have a decent amount of videos that stay without being taken down, monetize it and start a new channel. Rinse and repeat this until you have several channels and a nice extra automatic income from them. Expand as far as you want your wallet to go.
