Just like in subject. How do you converting cryptocurrencies into cash? For example in Poland I can convert in so-called bitcoinmat from page shitcoins.club. I don't know how is it in other countries, so please reply. Thanks 
Wrhen I was a newbie I'd always need the help of local exchnages to convert my Bitcoin to cash or transfer it to my bank account straight. But these people always don't buy at the exact rate, rather they minus it, cause that's a way for them to make their own gains. I was doing that until I discovered Luno wallet and also found out that most of them that are local exchangers were using Luno to do their business as well. So that is how I started using their wallet since it allows me to withdraw to my bank straught away. You can also make use of BitPay debit card.
