The major difference between Youtube and 3 Speak platform is,Youtube takes at least a year to grow your channel if you are doing everything as per their policies, which very difficult.On the other hand ,3 speak in a platform where you can make money from the very fist video .The amount you can make after a year of effort on you tube, you can make it on 3 speak from the very first month.and remember guys best thing is.the price of steem is very low at the moment and it will go upto $3 at least,so if you hold your steem coins that you earn everyday from your videos until price goes upto $3 at least then you can make way more than youtube.
