Did the list grow more because it now looks like many more exchanges are now offering?
The list grows every 2-3 days

If that is the rate at which the list grows, then we have to be careful of how we invest in them. Most especially owing to the fact that there are scam exchanges, which could also lunch scam IEOs.
Then sometimes, some may not be able to detect that the project they are about to lunch is scam and that there are a lot of fake things about them, most especially claiming to be what they are not.
