Welcome!
The first time I used BTC I knew immediately something was missing. The second time I used it I knew the 'mixers' recommended for privacy were also inefficient. That's about when I stumbled onto Monero and I haven't bothered with other cryptos since.
We're all also learning all the time. If none of us put any effort into growing our understanding of money, decentralization, or privacy we wouldn't have ended up here.
Anyways, welcome again and ask questions if you have any! Even if no one here knows the answers it may at least be a good discussion and someone will be able to point you in a helpful direction.
Same! Having everything built into an app is much more convenient than something like coincards.
