altcoin which can be an option for long-term investment is altcoin which is in the top 20 coinmarketcap, In my opinion, this method can minimize the risk of losses that will occur to us.
Yes but also need to be careful. Some of the top 20 marketcap coins will also be replaced by the others, just like the old 20 marketcap coins before 10 years.
And if someone has bad luck and choose the wrong one, for sure can not get enough rewards. Just my own feeling..
