What are the best ways to return to Bitcoin nowadays?

A few years ago, I was one of those Bitcoin enthusiasts, but as I got older and took on more responsibilities, other priorities emerged, and I ended up completely giving up on cryptocurrencies. Until recently, I had a somewhat pessimistic view of how popular the currency had become over time. Today, as a more mature individual, I'm thinking about long-term value preservation strategies. The economy here in Brazil is likely to collapse drastically (this has become a reality after the reforms carried out by the government over the last 8 years). The real estate sector is frighteningly unfeasible, and gold is out of the question, so I'm left with returning to Bitcoin. I would like to know the best and safest recommendations for starting to buy now, and whether it's really advantageous to buy at this time.
