My most recommend way is bot trading i've never tried it but also going to try and make it. I've seen some videos of it that really quite catch my interest especially when i am lawsy trader and it doesn't just trade for you and provide automation it also gives you profit by trading without any emotions attach. As long as the bot is properly coded and properly tested, i think there should be no problems with this.
You can use a bot if you want but do you know how to produce profits without a bot? If you do not then forget about building a bot or buying one, use your spare time and money to learn how to trade, do this for a few months or even a year and once you understand your method of making money in the markets completely then you can try to build a bot that trades for you, but until that day comes trade on your own not only you will earn money if you are good at it you will most likely find it very entertaining as well.
