Wow, amazing website! To the bookmarks. I was looking for crypto websites directory for a long time, but haven't found as good as your website is. Some directories that I found weren't updated for a long time, others listed too small number of websites.
I want to give few suggestions. First of all, about gambling websites. I think you have to remove 1xBit from your list. It's well known scammy bookmaker, you barely can find positivereviews about it. Another thing - prepaid debit cards. Spectrocoin don't have debit cards since the last year and they still didn't found new provider.
And few websites which you can add in my opinion.:
https://coingate.com/ Coingate - crypto merchant service. Maybe it's not as popular as Bitpay or Coinpayments, but it;s reliable service in market since 2014.
https://www.coinpayments.net/ Coinpayments - one of most popular merchant services.
http://preev.com/ Preev - Bitcoin,Litecoin/Doge price tracker. It's very basic website with limited functions, but it's one of firts choice when you just want to check current Bitcoin price.

Thanks for making this website. I'm not new to crypto, but I found so many interesting and new to me links which will be helpful for me.
