I have been using my mails for sometime now but recently I tried to register one of this Bitcoin investment schemes. To my surprise someone was able to withdraw all my fund when the investment matured. I tried to changed the password and when I did so I was not getting the password change link for several time so I decided to check spam to see that anytime the massage comes action is taken with numurious changed passwords. I was able to changed the password at the main site but I couldn't use the one that I used and when I checked my emails I discovered that another changed of password has been initiated after I did my own. I am using Gmail app with all my emails signed into it together with my Yahoo account. Now I don't seem to have control of my emails as every step that I take to secure all the emails fails. Please what can I do to secure my emails or detect where the problems are coming from?
