Worst mistake is that in 2010 i buy a second hand ps2 for like 25 btc when it was like 2 dollars a coin, the seller forget about it and finally remember them when it is $1200 a coin.
Sometimes i still cry about them lol
So you send the coin and he never come back. The seller only came back when 25 Bitcoin is worth $1200 and than he send you the product? At least he send the product to you and not taking the 25 Bitcoin away. If I were you, I will ask for a refund. I rather risk the seller not sending me the product than being ripped off.
No the seller was my friend, after i paid him i get the ps2 that day. He said he would sell them when btc is 5 dollars a coin but he forget about them. When it reach 1200$ he suddenly remember it and cash out.
