As a general rule, please be
extremely careful what you discuss or send in private or e-mail.
You have to make sure you don't send things that can get your coins stolen (wallet files, private keys,..) and also allowing others access your computer remotely is a security risk.
The security of bitcoin or usage of trading always depends on you because if you are taking care of your own bitcoin, you will be able to use bitcoin safely but if you doesn't care about your security, you will surely lose all of your bitcoin especially when you have a bunch of bitcoin. You are also going to get easily tricked by scammers if you don't have enough knowledge about the security of bitcoin. You should study about the security of bitcoin first before you invest on it.
