Every investment has risk and altcoins price rises whenever bitcoin price goes up. Altcoins are not volatile like bitcoin. They are like stable coins and their movement is very slow and their value is not encouraging to invest. Op I must tell you the truth that trading is must more better than investing in altcoins because their some altcoins that you will invest for like three to four years yet the value is nothing and not even up to a dollar and if you learn trading and you become a successful trader for a year, you will make enough profit from the trading. So I choose trading to altcoins.
