I botted my main from lvl 3 to combat lvl 98 and total lvl 1700 something, not amazing, but I was doing great always in Mirrored mode and I stayed away from Runecrafting/woodcutting/minning for the most part.. Too risky, I made my money by smithing mith and addy dart tips, eventually I quit and then came back and got him banned within 2 days getting greedy, but when I was doing it smart I was only botting 4 hours a day spaced apart throughout the day along with legit stuff here or there for a few hours a week.
Sand crabs are really risky though, I'd do Al warriors to 40-45 attk/def/str then go to experiments until 70, it may be slower, but MUCH safer imo
