These guys at least respond to my messages and pick my calls every time. And they fix everyday online review meetings for work that is been done for me. I dunno about what others say, but here is what I have to say: I have outsourced this work to 4 different companies before. Each one of them are terrible when it comes to responding once the payment is made (Sadly not many even know what Crypto business is all about). And finally Am left hanging. These folks at BitExchange are the 5th and Am happy. I have got 2 scripts installed by them and they work good. Am now getting a customisation done and Am happy I get a call from them everyday at 9. I see rapid progress. Thanks folks. Keep up the good work! FYI: I write this review so others make an informed decision when choosing your blockchain or Cryptocurrency development vendor.
