I was wondering myself what everybody is using.
I'm making money and making good choices so that part doesn't seem to be an issue with me but I think right now I've kept it really simple. Have no idea what people talk about gas fees and stuff like that but I want to get even more into it.
Right now:
Coinbase to buy. That's it. I was looking at some others like Binance.US, Kraken, Kucoin, Gemini. Coinbase using my debit/bank card. The others want wire or ACH and then some might only have a few coins that I'm interested in that Coinbase doesn't have. Binance say they take debit card but it's never worked. Customer service seems to be horrible with all these places.

Just got the Ledger, will dive into some tutorials, looks like you can buy via Coinify using Ledger Live. Might give that a try.
