Going to bed, just one fast example bevor i dig out some more to understand it complety:
Here a statement from the Digibyte page:
DigiByte is unique in the fact that it has five independent mining algorithms that further enhance DigiByte’s security.
So, again following your logic i 'am promised here that it’s unique … you read it, but in 2 or 3 months they fork and will use only 1 or 2 algos. It’s no more unique, it’s not more a fact and so on…
Actually it’s a real case, they really fork and change in 2 or 3 months away from these algos.
