Hi,
I just recently bought 1,000 bitcoins and want to use my position to be an OTC trader. I understand that many people are selling and buying bitcoins at 5%, I thought I can sell or buy bitcoins at 3%. So those who are selling and buying at over 5% can buy or sell bitcoins from me to sell to their customers to make 2% or higher (this figure comes from over 5% - 3%) so I can make 1% or 2% and those selling and buying over 5% can make the difference. It's kind of arbitrage for otc traders.
PM me if you are interested

It is very difficult to believe that a person who invested about 600,000$ investment has invested them to do arbitrage, although it is a way for making money but the way you are spending your time to make money seems a bit different with others.
Arbitrage is a safe way to make money. Although it is less profitable, but it has much lower risk than trading.
Arbitrage involves simultaneous buying and selling of a stock in spot and future so that we can gain from a difference in the price. To be profitable, an arbitrage trader has to do it often. The true arbitrage trader does not take any market risk. He structures a set of trades that will guarantee a riskless profit, whatever the market does afterwards.
Yes, but the profit is extremely low, I do not know exactly how much it is, but the guy who has only 600,000$ bitcoin is already rich, who does he need to do small profit arbitrages? It is the thing which does not seem logical.
If they want to invest it all if they can't get profit 1% a month its already high amount with 1000 btc , but the price is not stable no one knows what is the price of it tomorrow, if I am him I will exchange it to Fiat first, and find a good investment in fiat money.
