Ahoy there

Im a beginner with electronic currencies and started using Yobit few days ago
I would like to know what types of common mistakes newbies make and what to avoid in early days
Regards
The mistakes that newbies do is that they do not store the private key somewhere safety but since you have joined trading in yobit then you should care more about the coins that you trade there because most of the altcoins end at few satoshi.
