Other than Coinbase...where can I purchase other crytocurrencies? What would you recommend? I have a small amount of Bitcoin and Litecoin now.
Poloniex is one of the best exchange and you can buy all crypto currency here.The transaction fee in the poloniex trading is very very less compared to most of the other exchanges.Bittrex is also a good exchange which is having easy platform so everyone can buy in this exchange.But choose what coin you are going to buy then research that coins are available on that exchange.
