Hi, new here just to say I and  friends are after much research, are using group bitcoin.com.  As stated here we  members are going next month to an event  at their new place,  exellent service, they are always available to help and answer any questions, they answer e.mails  quickly. They are also aware of the technical difficulties of the mining, and change their rigs every rear or more, these two guys are genuine and you can go meet them,  so glad we found them.  I know we all have to be careful, but their are some genuine people out there,  we  just have to  be dilligent and check things out. We are  very pleased with group bitcoin and returns to wallet are on time.
