Look, I spent some time researching which is the best bank to invest in and I found it interesting how everything has changed in recent years. It used to be that complicated thing of going to the branch, now you just download an app and that's it.

It depends a lot on what you want to do. If you're a beginner and want something simple, Nubank and Next are very accessible. Nubank integrates everything with your checking account, which is practical. Next is more conservative, focused on fixed income and funds.

Now, if you want more variety and are willing to explore more, which is the best bank to invest in in this case? I think C6 Bank and Banco Inter stand out. Both have good cost-benefit, zero brokerage in many things, and the app is very intuitive.

For those who want something more sophisticated, like operations with derivatives and COEs, XP Investimentos is strong. It has real tools for those who know what they're doing. BTG Pactual is another, but that's more for investors with serious money.

Sofisa and BS2 also come into the conversation, especially if you want international investments or want everything integrated into a single app. But honestly, the best bank to invest in ends up being the one that makes the most sense with your style. Some prioritize zero fees, others want more products, some want a nice and intuitive interface.

What I think is cool is that nowadays almost all of them have fixed income, stocks, and funds. The real difference is in fees, app experience, and more specific products. So before choosing the best bank to invest in for you, it's worth testing the interface itself, seeing how it feels to navigate inside.

A few details: if you're going to trade stocks, pay attention to brokerage and custody fees. Fixed income is usually easier. And if you want international investments, not all offer it with the same ease.

Anyway, the good thing is that you don't have to stick to just one. You can have accounts in two or three and use each one for what makes the most sense, you know?
