I currently use the Bipa app to buy Bitcoin BTC and then transfer it to my personal wallet (BlueWallet), as I believe that "neither your keys nor your coins". However, with the new 17% tax rule on cryptocurrency profits in Brazil, I'm concerned.
My country recently considered raising taxes on crypto asset ownership, but so far nothing has been implemented. Our country also imposes taxes, but they are limited to trading activities on regulated local exchange platforms. While anonymity is something most people desire, it can sometimes be difficult to avoid due to the restrictive regulations in your country of residence. Some of the advice provided may reflect your wishes, but reporting taxable assets to the government is also a good idea to avoid future complications.
What i have realized is that, bitcoin have made taxation very difficult in the sense that with bitcoin one can avoid tax for as long as possible as far as that bitcoin holder make use of decentralized bitcoin network to carry out their transactions, since you only get taxed when you have contacts qith centralized financial institutions like cex exchange and bank's.
