This will be quite risky for some people who know how because getting help opening a bitcoin wallet from someone else has the potential for them knowing your private key so that when a lot of bitcoins are collected, security is very worrying. My suggestion is to change to another wallet if you intend to invest it and leave the one made by someone else as a lesson for opening a wallet. Your account was created a long time ago and it shouldn't be difficult to create a bitcoin wallet because there are lots of discussions on forums about bitcoin wallets that are safe to use.

How can you possibly help other people when you yourself don't understand how to create a bitcoin wallet even though you have been actively registered on the forum for quite a long time. Read a lot so that you have broader knowledge because teaching other people to knowledge like yours will not provide comparable knowledge to other people.
