not sure if this is serious or sarcastic

I am serious send me $10 to my wallet and post how much you sent me for security along with your wallet address and I will send you twice as much back, and make a small profit for myself in the process. I don't charge a fee...Where will you get a better service than this anywhere else on this forum???
If you wish to take advantage of this opportunity before it's no longer available, just ask me for my wallet address with the amount you plan on sending and you'll see for yourself this is not sarcastic nor a scam and you in fact now have double the amount you''ve sent to me in less than 1 hour.
Any coin you send to this scammer will be a donation. Unless you believe he cares for your more than his own mother...
