Don’t hold the coins. Soon as you get wallet, buy and transfer right away.Had the worst experience ever dealing with this source. Not sources fault cause I so wanted to try the product but fuck any source who wont deal in something other than bit coin. I spent 250 on Friday to have 150 today and after transfer fees I couldnt even buy the product. Why do you All put up with this shit. This bitcoin shit is a fucking nightmare. I'm out 120 bucks in 2 days and I didn't even get the hgh. I told opti to consider another form of payment but crickets. I gotta now go shopping for a reliable source. Maybe goodlyfe hgh will help.
