Hello everyone .. someone can recommend a good online trader that you can buy and sell all cryptocurrency (even ripples) thanks
Ges, you are looking for an exchanger. I can suggest a few legit exchangers:
To buy crytocurrencies with fiat, there are for example Kraken, Bitwala and coinbase. For trading cryptoconencies you can go to cryptopia, Poloniex, Bittrex and Bitfinex. That are only a few examples. You will also find infos on service discussion → exchanges:
https://bitcointalk.org/index.php?board=223.0The 3 exchanges with the biggest popularity are Bittrex, Poloniex and Bitfinex.
You cannot buy crypto with FIAT on any of those exchanges though!
You can purchase Bitcoin with FIAT from Coinbase and from Bitstamp but you will need to confirm your identity.
A note on Coinbase, if you purchase your bitcoin there you can avail of zero fees by transferring you bitcoin first to GDAX,
it is Coinbases own exchange with limited crypto currencies.
from GDAX you can send your bitcoin anywhere else I.E Bittrex with zero fees.
