$BTC Many people here ask which currency to buy, I see photos of wallets with 100, 200 reais. The truth is that these people will lose almost nothing they have. My advice would be to stop trying to become a millionaire with 100 reais, save as much money as possible and in about 2 years start buying again. For beginners, now is the time to get out. Many currencies have already appreciated more than 10x (example $SOL ). It is unlikely that any currency will fall if it appreciates 10x from now on, the time to make money is in the low. Of course, there will be some that will boom, but there is no way to predict, and even if someone rides a high, they will not know when to get out and will end up losing everything again. (Remember that this would be for beginners)
