I would recommend you to watch on cmc and see top20 coins/tokens with highest trading volume . Also be careful and watch at history price of every coin/token . Don't invest in coins/tokens with lowest trading volume
invest to certainly has risks and it depends on each other's self confidence. sometimes coins / tokens under the top 20 can make a profit. maybe if want to be more secure then invest in Bitcoin or Ethereum because that it is a good solution and will avoid big losses depending on market conditions.
