Buddy polo are good, I can tell you that for sure but people on here do moan because there impatient and uneducated about how these exchanges work. If there is a delay there is always a good reason for it. Polo have never let me down in 3 years of me using them. There will be delays on any exchange due to the nature of cryptos. The delays are so nobody loses anything most of the time, so ignore all the bs talk people blog about here. They only care about themselves and fail to see the big picture. I hope this helps :)
