You bring up an interesting point on trading robots. As I am typing this the last price of Bitcoin has substantial gone done within the thousands (so within the hundredths it's extremely volatile). Although I don't know the numbers of trading robots I think by looking at the numbers when the spike had hit into the 11k and continuing to go up from a traders' point of view the opportunity for money to be made was inevitable. The highest point has been in the 19k and it's currently moving up and down in the 14ks. Anywhere between those numbers traders have been making money. If it steadies at around the 12k-13ks then things are looking good because it tells me that the numbers of actual users are putting their belief into cryptocurrency.
In war there will always be casualties and someone is gaining or losing, especially those that look it like a stock. When it went up $17k and now down $14k they are kicking themselves thinking they lost $3k. While true if they brought in at $17k it definitely looks that way but that is also not looking at the big picture.
I guess what I'm saying is not to worry about the robots. They will destroy someone's belief in the cryptocurrency system because as human beings we are emotional.
This is why I've advised anyone buying cryptocurrency, especially those buying at the hundredths to not look at it as a quick investment. It's not worth the emotional ride, especially if they are looking to cash out quick. However, I do try to convince them to buy to try and make a transaction to see how it can be used for tangible goods. It gives them a glimpse of what the future will be like.
But this does leave a small vulnerability that over time will correct itself because of traders. Because it makes complete sense in their point of view and I don't fault them b.c. if they have ten thousands of dollars to place and make thousands within a few seconds & minutes it's a very good trade.
