I completely agree with you on your investment plan and at any opportunity we certainly need to buy the Steem. With regard to the use of bots, it reminds more of the casino, since you can invest in any amount and calculate how much to pay at the moment, but no one will give you a guarantee that your investments will make a profit, because the purchased increase can partially be disposed up to 7 days payments, and here the end result is only the bot itself, this is roulette, lucky or not!
