I see a great potential in business of buying and selling bitcointalk accounts , can be done to grow bitcoin, buy account when ranking is still a member and sell them when the full member, I think it's a very safe investment, all things considered.
Others doing that kind of activity. Takes time but really sure earnings if done properly.
But make sure the account you are going to sell has really shown proofs that it is clean. It includes proper post, proper sign message etc.
