Views and members not the same. Looks cheap. But also worthless.
Just wondering if you can add 200000 members. Can't you add 1 million. Would sound better. 200k so small
Even if you add a million or 100 million members to your channel or group in Telegram, your channel will have a lot of members in a short time; after the days and weeks pass, you will find the channel reduced from the millions of members that were provided to the number of the actual channel before that, so If they are not real users interested in the content and filed of your channel or group, you will buy a bot service that is not even worth a few cents.
I am not here to be against the OP or hinder him from earning a living, but I am saying my opinion quite frankly because I lost a lot of money on these services that have no benefit.
