Hi; Wirex community manager here!
We offer a SegWit enabled Bitcoin Wallet with a mobile app; that would allow you to convert your Bitcoin (or 45 other Crypto's) into $,£ or Euros instantly.
Unlike all these new comers, we've been around since 2013, we have an inhouse dev team (our biggest overhead) who've created an amazing blockchain that links banking to Bitcoin (https://themerkle.com/what-is-w-pay/)
We also have an in-house support team that can help out when you get into difficult situations (https://www.reddit.com/r/Bitcoin/comments/70npq3/someone_stole_61_from_my_wirex_account_help/)
We wish you all the best in your journey for a new Bitcoin wallet provider; and hope that you consider Wirex:
