Question...
I put my 'Coinbase BTC wallet address as my BTC wallet on Hashflare and pressed 'save'
So now my Hashflare BTC wallet has the same address as my Coinbase wallet.
So, if I request a withdrawal from my SHA-256 account, if they put the BTC in my wallet address,
will it instantly appear in my Coinbase BTC wallet?
I am scared, and I am not sure if I will ever be able to withdraw my BTC earned on Hashflare.
Do they even service United States Customers? Will a withdrawal be successful?
Yes it would go through since its a btc wallet after all just make sure you are putting btc wallet rather than eth wallet knowing that coinbase do have that coin too. If i were you on your case i would rather choose up electrum because it is somehow safe on storing my bitcoins on the wallet which i do have the possesion of my own private keys which you cant really find or possible to access on coinbase since they are 3rd party wallets.
