Would infrequent (once a month max) BTC purchases from Coinbase be too sketchy in your opinion if purchased using my personal bank account? They would be smaller (no more than 200 USD and usually below 100 USD) purchases.
I was going to post in r/DNMnoobs but I need a fast response and this sub seems much more active. Sorry for any wrongdoings.
For such small amounts, that shouldn't be an issue. You can tumble them for another layer of anonymity.
