Minehut says on their home page, that, they have up to 500 max players (they don't) and the startup time is instant (it takes a few minutes). MCProhosting is about correct, but the Aternos one is totally messed up. They say you can only have 10 players, but you can actually set it to whatever you want. Believe me, I've tried Aternos and it lets you.
I was just a little mad about this and thought I should mention that this is total cap.
Just as clarification, I still use Minehut and I think its an OK server provider for me and my friends to play on. I do not want Minehut mad about this, I just want to make sure that they know they are wrong. I do not want any trouble with Minehut.
And I totally understand if they put that in for purposes to make them look better, and I thought i would just mention it. Please do not be mad at me.
