U make all 3 wallets then ( coinbase, blockchain, electrum) and then send message from every wallet to same address. U cant mistake then.
Can u imagine luck on that guy face when he check his wallet and there is 1.6 btc recived? Wow. Anyway maybe he removed all his money to some other wallet and abandon this one.. eh.. I would like u to get coins back, but its hard.. people are not so honest.
yes a lucky day for someone !!! and a expensive way for me to learn... but learn, i have and a lot, more thanks to all of you ... thank you all for your time and concern...
