I had bitcoin via Changetip but it closed and I transferred coin to a wallet which I don't remember. I have bitcoin via Changetip but Changetip website closed and I transferred coin to a wallet which I don't remember. My question is how do I retrieve my bitcoin? Any help is appreciated, thank you in advance.
You'll need to remember what wallet you used to clear out your change tip account. Without that wallet, you'll be unable to recover/spend those bitcoins. Try searching your email, browsing history, etc, for clues as to what wallet you used. Best of luck.
