First, most good trading, crypto or not, is systematic, which is automated.
Then, from what people have told me, crypto is a highly inefficient market so huge of potential for market-making strategies. Tons of arbitrage opportunities between the various venues, centralized and decentralized, mostly uninformed non-professionals so non-toxic flow, huge spreads, etc.
It's like the traditional tradi'g world but 30 years in the past.
"Grid trading" is apparently just a weird term for placing orders proactively on multiple levels to obtain a better queue position, useful for increasing edge capture on exchanges with price-time matching.
There are a lot more sophisticated techniques you could transfer from the world of traditional electronic trading. Of they're successful on much more competitive markets, no reason they wouldn't work on crypto.
I don't know, but it seems to be. In general though, if there are easy profits to make it is because someone on the other side is willing to lose "a small amount of money" for a long time knowing that when things change they will make a ton of money fast, on the backs of all the people they lost to.
For starters, if you can make money in automated trading, why would you not make all the possible money yourself instead of telling other people (or writing the software) and splitting the profit? This question is one I ask anytime someone mentions easy trading, and because I've never heard a good answer I stay away.
To do better than average is possible, but it requires a lot of deep study.
I wrote a trading bot, it worked well for a while and made money until Mt Gox shut down. I open sourced it because I thought it might be interesting for others to see.
I updated it for Bittrex, but didn't have enough capital to actually make it work.
Now everything has gone up so much, and I'm bearish on crypto in general, so I don't want to have any money invested in it.
That's why mine is available, and I'm not currently trying to keep it running.
Why? After buying and selling side fees, is it easy to make a profit in an automated way with crypto?
