The "Estimate from PayPal" cryptocurrency scam email invoice below, which appears to be from service@paypal and claims to be from Crypto Currency is being sent by scammers. The scammers are attempting to trick their potential victims into calling them at +1 (888)328-4524, which is a fake PayPal customer support telephone number. If you have received the fake PayPal invoice, please do not call the telephone number in it, just delete it.
