You can increase your BTC holding, you just have to know how to set up the bot and what to expect from normal market activity.
If you had 20k at 130 USD, then you at 900 USD you should have made (in fiat) about 70k to 90k. When it comes back down to roughly about the same level, your bot will then buy BTC and increase your future earnings as it swings up again. Of course this may take months and a very volatile market. The next time (assuming the same level of volatility) you should have alot more BTC than you started with.
Though honestly, if you are looking for short term gains you'd have to look at a BOT that can look at different kinds of indicators and more than 4 thresholds. Hopefully B-Bot development goes down the same path as Haasonline.
I'm looking for longterm profit, i runned the test with different settings and i never got a way where it increase btc holding...
I'll continue testing...
Please note that you are testing configuration over a very long time period. In reality there different phases in the market where different settings work best (e.g longer time frames during slow and steady trends to filter out the small movements, smaller time frames and lower EMA values during triangle formations to catch the breakout ASAP etc) so real profit can much higher when you monitor the market and adapt the settings from time to time.
And finally to some (to me at least) running a bot is not only about maximizing profit but also about managing risk. I definitely sleep better knowing that the bot would get me out in case of any unforseen circumstances
