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
I also see that but the rich can be more richer by that kind of thing. There are a lot of advantage of this and that's why it became popular on some person and improve like this. I see also that it can change a life by human person on no matter how old they are, the reason only was the mind of the person on how he/she cope up on this kind of work to change for his/her future.
