For me, altcoin has many advantages, one advantage is it gives to the individual money to sustain the basic needs, It also reduce the increasing number of unemployed in some countries, The people who work in bitcoin develops the ability to reason out, enhanced the English proficiency, that's the some advantage of altcoin
It's changing the life of the society and you can make a big money in the short term without hardworking. So I think this is the best investment and you can making a huge money in the future without harmless
It is true that we can earn more money by trading altcoins but compared to bitcoin, it has more difficulty in recovering after its price go low. The tendency is to sell it while its hot because it is very risky to hodl an altcoin. The payment sometimes took very long before it is given to the participants and we known how worried we can be because there are altcoin ICOs that turns into scam.
