Re: [ANN]ROUND - CS:GO Competitive platform! ROUND IS WORKING! CHECK IT NOW!
I am sure tha allow by amount only is a bad idea.
Can you explain please why so? Interesting to hear your point of view. 
Its easy to implement. In dev console i have seen api "roundcoincoin". And i have notice there was variable "online" with parameters true/false. Well, I'm looking forward for this helpful feature:)
In my opinion It might serve like evidence that developers working as you said "to implement this feature".
