I don't think that everyone needs to read about it ..
Because
etherum
Bitcoins
Litecoin
Bitcoins cash
Are the ones really making the news...
Everyone's own thinking May differ but it's for an individual to decide what to invest it
if I invest long term, I think bitcoin is very good. this is the first reason because bitcoin is the standard price of all coins, second because bitcoin is the parent of all coins, and thirdly because bitcoin spreaders are around the world and for several other reasons, all the very good potential in the future is in bitcoin.
