which coin is good to invest for a long run after bitcoin? I do not have much knowledge also tell me best exchange to buy coins.
I will recommend that you buy more of ethereum and Bitcoin Cash because as Bitcoin market price increase they will also increase in value in almost the same proporsenate and you will earn a lot of profit at the end of the day. If you are looking for good exchange then I will recommend Binance, Okey, Poloniex and bittrex.
