This is the best exchange I have had the pleasure of using. Before joining, I was used to paying high fees and not getting any decent level of security or peace of mind with my money. This is no longer the case with The-30k-challenge, every coin I have sent has come through on time with ZERO problems. The volume of coins available for trade is immense, the user interface is easy to use, and everything about this place is great. Love The-30k-challenge!
