i keep an eye on this service but as for me, the 3-5% you say for loading is very many to loose one the way. better withdrawal to bank at 0.09 commission that i have from the exchange ... 
of course this have some negatives also but not 3-5% !!!
Go for spectrocoin or xapo, they only charge 1.5-2% of course this have some negatives also but not 3-5% !!! what's with all the hype about 5%?? where is it coming from? someone shouted on the corner, now everybody spreading the rumour?..
So how much is it? i don't know, i read the post about 3%-5%. is this right or wrong?
Can you name us the % that is this service working? We not need a hype how you say, i prefer facts
and i thought this user said that from experience...wait for your reply
