Too good to be true, it's not true.

12 hours to make x10 it look like a pump and dump group in which you won't even be a participant but a victim.
As for "BeInCrypto" I'm not sure since the link you posted is marked as "Suspicious link removed" but I supposed it's a referral link, they will earn a commission from your deposit or trade

If it's your first time buying cryptos what about using an exchange platform or a P2P marketplace instead of crawling on Telegram groups?
