Who has done it and what service do you recommend? Coinbase? I would be working from a brokerage account to fund. Want simple yet safe. TIA

I have some purchased through coin base, and I have been using Robinhood for about 3 years now. I have several different cryptos now and never had an issue with either platform. I had a bunch of stocks with Robinhood and figured I would try getting into Bitcoin through them and have been pleased with the results.
