There is a crypto coin that I like and I wanted to buy some on an exchange.

All these exchanges are

1. Super scamy, often in dubious jurisdictions

2. From the layout obviously targeted at very young people

3. The appearance, interactions and handling resembles more an online casino.

Sounds similar to registering a domain name.

None of the online gambling I engage in is regulated in any way.

Coinbase is pretty heavily regulated.
