Ok Thanks for your Prompt and valuable reply.
I would never try this bitcoins now. I had lost around 2000$ in it. My foolishness.


Thanks for your comments.

So how can we trust this bitcoins investment. Is there any trusted agency or applications so we can invest there.
Nowadays in FB many people post that for 100 $ you can 1000 $ just by investing no legit like that, why cant bitcoin company block them.

Is it a scam, they told me they are from bitcoin mining company and they are professional in their job so they are helping us to get more bitcoins.
Is there such company available. They even send their videos of such mining hardwares used.
Will I get my money back? They Provided my a Private key on amount of 200$ (Private key is only 8 alphabets containing two digits). Also they told once I buy the key I can transfer the bitcoins in other account but it was not possible.

My Dashboard on Blockchain app show 732.2232 BTC nonspendable , what does it means.Is it possible to transfer the bitcoins to another wallet, from where I can get the private key.

What is watch only address and from where i can get my private keys in blockchain to transfer the bitcoins to other account? Does the non-spendable bitcoins can be used?
