Static IP cannot remain same always.
Many times internet line is down due to various reasons so ISP change its provider or we change from broadband to mobile or some other network.
In this case static IP can not remain same.
In case of network failure we cannot switch to another network. It can cause trade loss during that period.
Since static ip we are not able to change location. We must stick to only one location. This is not fair.
Retail investors price of static ip and multiple static ip could be high.
If you dont want retail investors to survive then please let us know, we retail investors will try to do some other business.
