[WTB] Trading only 1 PAIR

Dear friends from BTCTalk,

Since I've been on mining, already one year, I've been looking for ways to increase the results. I've tried some manual trading, I tried automate trading tools, most of them open source, I've tried some gambling strategies as well... but I wasn't lucky.

I'm a holding in long term BTC and ETH. And what I need is some kind of system, that allows me buy and sell this pair, to get more BTC and more ETH without risk.

In other words, I'm looking for a progressive trading strategy, or system, that would allow me to increase further the amount of ETH and BTC I'm holding.

As well, I wouldn't mind to add another pair, as it could be Ripple, or Waves.

I want to operate only on some safe currencies per se.

Would you give me any recommendations?

Kind regards;
Chris
