I don't see this happening not because I am limiting the amount of growth Coinbase could witness, but because of several factors which include:

1. Coinbase with its base in the US will have to compete with other big banks that have been in existence for centuries, they hold major positions in government, they donate to political parties, they have the capacity to lobby laws. The moment their positions is being threatened, then you see the big hand of the law coming.

2. I dont see myself using Coinbase not now, not in the future and a lot of other crypto users not in the United States because of the stiff KYC policies that they have in place.

3. The issue of banks originally negates one of the founding principles of bitcoin. Keep your fund yourself is the rule and who says Coinbase who will continue to a target for hackers. Hopefully it will remain stronger.
