there are so many places to buy Eth, but I recommend buying it at
https://www.coinbase.comthe coinbase fee is very little
Coinbase is the very mediator to buy the ETH, but we need to pay a higher transaction fee when using the credit cards, now Binance exchange is also accepting the credit card from the different parts of the world, that's why before buying we need to watch the reviews where we are getting less fee for purchases.
i heard coinbase is getting bad and yes they also have a high fees but binance is a good one .
kraken.com , poloniex.com, shapeshift.io
For now I'm avoiding using poloniex exchanges and its better to use other exchanges. Many issue release up already in poloniex. But i suggest to hold your ethereum in Mew wallet or Myetherwallet.
what kind of issues ? im not aware with that . i still believe that polo is on of the best exchanges .
Well, in most cases I prefer to earn ethereum for some services, but if I need to buy it, then I uses my card and Indacoin exchanger. it is valid not only for ethereum, but for bitcoin as well.
I don't think there is a big difference in both crypto , I mean it is easy to buy each of them.
I would like to buy it directly on exchange, but now this feature isn't available everywhere
eth and btc are both popular so theres no really difference at all when buying them , anyway there are exchanges that accepts credit cards for cryptos or better if you can use third party credit card exchanges and convert it to other payment method first .
