There are actually a lot of trading bots that works perfectly fine with some people, such programs have increased in numbers since 2019. Cryptohopper for example is a famous trading bot, I've seen its name probably for 1000x already lol. But I love exploring and I've encountered more programs other than Cryptohopper like 3commas, Zignaly and Kryll.io - All are quite known in the industry right now.
Another trading bot has been launched this month as well, KuCoin's trading bot is the latest in my radar right now though I am still not sure how this program will play out. Well, the current price of ETH looks interesting and positive (see:
https://trade.kucoin.com/ETH-BTC) I am happily making trades right now, some traders must be running theirs with ETH as well I am sure of that.
Ive seen this bot on my KuCoin app made me curious as its new on the app so I checked it, learn it was a trading bot then tried it and its pretty cool. Havent had any losses when I run bots, tried ETH too just like what you said and DOT and it made me profits instantly because of the volatility good entry point I think is whats making it better to use. Tried crypto haooper and bituniverse before but can say this is better version. I will be trying the DCA too they said thats much faster than the classic one good range gives me good profits.
