I need a website to buy btc with the following requirement:
1. buy instant: not like coinbase, you just have certain limit instant buy
2. no buying limit: same
3. transfer instant or relatively fast
4. accept paypal or ACH from US bank
5. fees or commissions are reasonable
i've tried some but they are not all good, can someone recommend any?
I would say, answer depends with your Country of origin, each Country with active Bitcoin users have their own exchange site, it's much better if you transact with them so that if there's any trouble, you know where to reach them.
