It depends on your ISP...
50-65kbps can be absolutely normal, but it also can be absolutely wrong...
We need to know your upload and download speed from your internet service to say if an average of 50-65kbps is normal or not...
In other words, if someone says he has an "x bps" connection, it means absolutely nothing without further information. What is x? download speed? upload speed? total upload/download speed? Is it his theoretical speed? Is it the average total speed? Is it a number he got from his ISP? Is it a number from some monitoring program? what?
To say which type of connection you have, you always need to tell 2 numbers: the upload AND download stream speed figures you got from your ISP..
