If you are new to purchasing Bitcoins and want someone to help guide you through the buying process, then Wall of Coins might be the best Bitcoin exchange for you. If you have to make a deposit, then you are at much bigger risk of losing money than if you use something like Changelly where there is only a small window of time before your exchange goes through. Once you locate a seller, you meet up in-person and conduct the trade. Management takes a security-centric focus which is a must in the crypto space. Kraken’s fees are quite confusing.
