this is my recipe for success with trading bot:
1. code it yourself or be able to access to the source code
2. make it a grid bot and spread the grid +/- 100% range from the current price
--- NO LEVERAGE
--- NO STOP LOSS
--- optional: increment the order size: the farer from current price the higher the order
3. take profit at minimum, don't wait for +10% gain. get the minimum (of course consider the fees).. on average it's around 0.4% gain
4. only limit orders + post only
5. don't interfere with the bot
6. enjoy
It may happen that you stay days or even weeks with unrealized loss, but ultimately the price will recover and you will close the trade at a win.
When the trade is done repeat, in loop, forever.
like this i was able to grow my btc bag by 176.56 % in exactly 365 days, closing ONLY profitable trades. Not a single loss was taken (and i have proofs)
Of course a good trader can do this gain in a few dozen trades maybe, but he will have to deal with bad trades and losses.
Of course (2) there might be better solutions or strategy compared to this one, but well... this worked for me and I'm not changing it.
Of course (3) if you're trading a shitcoin that goes to 0 or pumps like 1000% in few minutes, you might lose all. if you're trading btc you're pretty safe.
sorry english is not my first language, i hope this was clear..
if not, i can answer all of your questions.. maybe..
also: don't sell the bot unless they're offering you a reasonable amount
