/**
FOREVER ALONE CLUB (FAC)

Is a Decentralized Meme Coin deployed in Binance Chain.
We aim to be a SafeHaven for all the Alone Degens.


In the Long run, Team is Looking Forward on Making This Token an Utility Token for "TINDER" inspired Community; where Degens Can Match with other Degens.
Upon Making an Account, Degens will have to link their Telegrams so when Matched it will automatically show to the both party and from there, they can start a conversation.
Aside from their Telegram they can also put their Favorite Crypto Coins and other Basic Information in order to let other degens know their basic Similarities.
