Yes, you can open a shop on the same street and make more money from it.

A big mistake that many people make is that when they see a currency that has risen by 40 or 50%, they run to it and buy it and put those behind them and those in front of them in it, and then they go back to slap themselves when its price goes down! Things here do not work in the same way that when a mobile phone shop opens on a street and makes a profit and works, the entire street must open mobile phone shops!
