Some P2P traders also take advantage of the chat option that they have with a customer that they are doing business with either buying or selling and they go ahead to try and negotiate to their own advantage to have some more financial benefits from the trade. Sometimes you find out these traders come along to tell you to accept an amount of money slightly lower than the amount of money you are suppose to get from the trade you are doing. There are traders who will accept, and this is another extra way that P2P traders make money from centralized exchanges even asides the home profits that they make from each trade, they also benefit from the amount of money that they are being tipped.
In the last few years, P2P has been spreading quickly with people doing well while using official accounts on centralized exchanges and also having side businesses as well, which are helping them in P2P because they can go ahead with their regular customers for this; despite having a commission, their profit is pretty good because during this P2P they are also chatting with their customer about its activities. These are helping them. I am really feeling risky, but people who are engaged and now have good circles, their profit and business are turning them good ways. Regulations are strict, but with mutual understanding, using third party accounts and taking more profit is also happening because there are still many ways to skip official channels, and staying in this possible maybe a few people are having this activity, but I feel possible.
Starting a business is the hardest part of this, because it eats a big chunk of your profit. Most of the time, buying and selling should not be this thin margin in most business ideas, and while some do survive it, most won't. Because the taxes and the costs of running a business are a lot higher than just a few trades, you gotta do big chunks; you gotta trade either a lot of times and make a profit, or you gotta do a huge amount of trading all at once. And not many people can do that.
So if you decide against starting a business on it, and just do it like a regular trader, then you are going to be checked by the IRS or whatever it is in your country, and you are taking a big risk with it as well, so it's not easy.
