Yes, I am using Poloniex to trade cryptocurrencies and to sell Monero and ZCash that I mine. However, I don’t want to go through the whole process of transferring, waiting, placing an order, waiting, checking, transfering, and waiting again every time I simple want to withdraw some Steem Dollars into my Bitcoin Wallet. BlockTrades save me from all this headache, that’s why I like it so much. :)
And yes, I’ve already considered getting myself a Bitcoin debit card. I’ve looked into BitPay, e-Coin and Xapo. However, as I am more of a holder than spender, when it comes to Bitcoin, I think I am okay for now. If I need to sell a share of my Bitcoins fast, I could do it via Coinbase or Kraken and then withdraw fiat onto my ordinary bank account in Sweden. But I am sure that in the near future there will be more choice of crypto debit cards to choose from. Heck, maybe our mainstream consumer banks will offer them!
I will be talking with @greekcouple on Skype this afternoon. They are getting a Bitcoin debit card from Xapo. I will be curious to learn about their experiences and impressions of it.
