Two that come to mind are Coinbase & Circle. I did a quick google search, possibly wrong terms. The information I got was useless. I am sure this has been discussed. If there is a good article/link on this it would be appreciated.
Hi, I am from the Philippines and I am using a coins.ph. Our Local currency which is Philippines Peso is converted into bitcoins through COins.ph and after that I deposit it to different trading sites. Well the negative thing about it is that there is a high spread between the buying and selling amount of Coins.ph. So I only buy bitcoins when the value of bitcoins if very low. In that way, I can avoid the loss.
