You have to be very careful and recheck everything. There are a lot of scams and they are becoming more sophisticated, be vigilant
vigilance must be really applied in everyday life. the most effective way is to buy cheaply when the market price is red. Bitcoin is the safest place in my opinion. because bitcoin has proven able to compete in the market. Don't invest in coins that have just appeared or don't have experience in the market because it's very risky if the coin can't compete it will die.
