The number of views on your Twitch channel significantly determines the authority and quality of the channel. A channel with more viewers is an indication that the particular channel is performing well. The number of Twitch viewers that you should have in your particular video entirely depends on what your goals are.
It is advisable that you carefully lay down your goals and then aim to attract live viewers. If you are not able to attract more viewers in the initial stages, you can purchase Twitch viewers. GPC.FM has different packages for views on your Twitch channel. So, before buying, you can check the package for high-quality viewers and decide on the final one.
