Hi I`m new here. Here goes my first post.
I use the local altcointrader.co.za exchange. Initial reasons were that could fund my account doing EFT from any local bank account.
Once the funds are available, usually in 30 mins - 3 hours, I can buy of the available crypto currencies including XRP, BTC, ETH etc.
Once I bought the coins, I can withdraw any amount of the coins to my Kraken or Bittrex account. You would just need your XRP or BTC address on those or any other exchange that would accept the crypto deposit.
