When you initially connect with one user for the first time on the Instantgo platform, you will need to have a minimum number of points on balance to do so. Points can be earned easily or simply purchased. The number of points required will be displayed before you enter in that initial chat. After that, you can chat with the other users without using additional points.
When you contact someone on the chats, for example an expert, you can agree with them the price for their services or products and do a transaction between you. Instantgo is not part of those transactions that are done and decided between users directly. Other users may be willing to communicate for free like in a regular chat.
