Please help me do better, what do you think is good for this method?
If your not a scammer and you mean business then share your tips to interested people for free for sometime in that way they will have believe on you.
1) Need only login+pass of your account. You can change it in any time if you want. I cant steel your account.
I have a very simple question for you , can you fund your betting account and give out someone the password as you asked others to give you theirs?, Then if yes share your password since you want people to have confidence on you that your not a scammer as someone giving out his/her passwords means nothing to you. Do you know that giving you password to my account has given you full access to my account, therefore I'm not the only one control of it.
