I have lost my etherium wallet private key.Could any one know how to recover my private key.
there is no way to recover the wallet if you forget your private key and did not record it to anywhere. you should check and remember if you noted it somewhere or not. otherwise there is nothing that you can do.
A way to recover your pv key is to create new ones. You can create using mew then connect to metamask, don;t forget to save pharaphrase. You are in land of crypto, lost pv key lost asset. PV key is the key you can enter to the banks you own. You should know how to secure your wallet by yourself. I hope you not loose too much and take the accident as the lesson to secure your wallet, use your personal laptop not share with others.
