Actually i want to know when we earn btc how can we get it to cash . Is there any secure website or something
you can exchange your bitcoins in ether delta ... CEX or poleniex that is what sites that is secured that I know .
and after that find a site that is secured and trusted . you can search it depend on your country..
here in Philippines we have Coins.PH where we can convert btc to local money or fiat and withdraw it on any remittance center like western union or cebuana or even banks account if it is connected to your Coins.PH account
