Has coinbase cut limits? I can only buy $400 from my debit card and 5K from checking. Is there a site with higher limits?
With Coinbase go to the verification page to see your limits by each method. Limits seem to be different for everyone. You should be able to purchase a lot more from Coinbase depending on verification.
Gemini is a nice site with low fees but they also have low limits. Cash App is another good site to purchase with limits of $2500/day.
