Buying Bitcoins the Bitit way is great for people who don't want to use their credit cards online to buy the crypto out of caution. But the $25 limit without documentation is kinda low if you ask me. What if I need around $60 to buy a game on Steam with Bitcoins for example. Can I just enter 3 different stores to take advantage of this so I don't give out my identity? I guess so.
I think they said their algo tracks users and credit cards - so you can probably do three purchases over several days and they'll let you if they don't then get a dispute filed with the credit card.
Honestly, the only way I see around this is Bitcoin ATMs that accept cold hard
cash. That way there can be no dispute and no fraud and people can buy as much as they want as long as they pay cash. Sadly no-one seems to have developed a cash BTC ATM.
