The safest way to get passive income is staking, but it must be noted that not all altcoins are good for staking. Try doing some research first to
find out which altcoins are profitable for staking, then another thing to consider might be choosing a trusted staking place. Because there have been
several incidents of investors becoming victims of fraud, don't easily trust platforms that offer big profits, but don't have a good reputation.
Regarding trading bots, I don't recommend using them, especially for newbies. Because trading bots do not really automatically provide passive income.
We still need to make settings for the trading bots used, wrong settings can result in us experiencing losses.
