I don't understand why you made this topic.
I thought it is an invitation letter to guests, customers. Is it a letter from your business or from Binance?
I don't think it is from Binance definitely so only one chance left, it is from your business. So where is the link of the invitation letter on your website?
Because it is impossible from your business, I move my mind to another option, it is your educational topic to guide newbies creating accounts on centralized exchanges for trading. In this guide, you teach them to open account on Binance.
Binance. How to get started? New user guideIt's worthy to mention
Reminder: do not keep your money in online accountsJust like the title says, the OP is giving tips on how to advertise Bitcoin and I think he only use Binance there as a sample on how can people get involved in Bitcoin but I think that was fast if he will recommend trading without introducing what is Bitcoin first. There is an introduction there but it was wrongly written. As @mk4 said, Bitcoin is not a trading platform but one example of a trading platform is Binance.
Bitcoin is only a digital currency or also called as cryptocurrency which is decentralized. He didn't put a link yet to invite anyone about their program because it will not start now but we still have to wait for 1 more month. I guess the OP can still learn more about Bitcoin and hopefully he will improve before the event starts.
