What I do to minimize fees is, is the following. I send money to Kraken (SEPA), buy XRP and tranfer that to Bittrex or Binance. The sending fee is 0.02 XRP, which is something like 4/5 cents. On Bittrex I change the XRP to BTC and with that BTC I buy the coin I want.
Now if I had used the fiat to buy BTC and transfer that to Bittrex it would cost me 0.001 BTC (which is approx 10 dollar). I’m a small time investor and usually buy for 100-150 dollar per month. If I would use the BTC this would really hurt my ROI
There are a few downsides though:
- I have to make sure the money is on Kraken in time (requires planning / regular payments)
- The price change during the transfer (XRP is not that volatile and the transfer is really fast!)
