Generally, newbies in any space tend to be erratic in decision making and even more so in crypto. Statistically, it's more likely for a newbie to blow his account than a seasoned pro even if they have the same amount to start with.
However, there are ways to earn that are far safer and guaranteed to not blow a young portfolio. The most common ones are airdrops, staking and farming. In the recent past, some CEXs have introduced new ones like PoolX which can also be a good avenue to earn since more often than not, it involves the use of stablecoin and guarantees your capital. Some very good hits for PoolX have seen upto 75% APR which is commendable by any standard.
Overall, I believe the above methods are good starting points for newbies.
Kindly share if there are better options guys... I don't mind earning like a newbie every time I can!
