in my book bitcoin7 is the best exchange to buy for everyday use, that is spending btc, not investing. they allow payment with paysafecards, i.e. getting my bitcoins is a matter of minutes, not days. i walk into my cornerstore, give them cash, they give me a paysafecard-code, i enter this into bitcoin7 (5% fees) and can instantly buy bitcoins. dead simple.

i wouldn't do this for larger sums to invest, but for buying stuff at the few places i know that accept bitcoin, it is perfect.

disclosure: i have no affiliation whatsoever with bitcoin7 or any other exchange, and you are welcome to use any of them. i do not spread referral codes. thank you.
