Choosing right altcoin is vital when it comes to investing and trading, I prefer to buy altcoin that is trending where it has high volume in the market. There is no safe altcoin but there are altcoins that have less risks because of its low volatility. There are altcoins out there that is currently trending like ETH where there is price rally that currently happening. The volume is also massive that is indicating there are a lot of people who are interested to buy ETH right now.
