My feeling too that a lot of the big moves are manipulated. I'd be interested to know what software tools you are using and what sort of rig you have got... any photos?
No software, it's an algorithm because it's a strategy made by a series of rules that you need to check before buying an altcoin. The entry is manual.
I had some good days because I found coins that were clearly manipulated and I joined the ride, normally I don't have those returns
Since yesterday's work on Bittrex platform, I'm struggling to find a good coin because all the volumes went down. ADA from 36K to 10K; XLM from 12K to 3K.
Took a nice profit on Einsteinium, but already got out. Just trading on Emercoin as mentioned in another post.
