I would do mining, fishing or woodcutting hope this helped you buddy

i was considering doing mining mines currently 55 get that to 85 mine some rune mate

You see all those people standing around saying "doubling money"?
Yes, they are scammers but most of them run on the same guidelines=
Usually most people give them around 10k, see if they actually double it, then give more (they are dumb enough to think it's an actual glitch/hack/w/e).

Anyway what i've been doing lately, is using the "if you do this one i'll give you more" tactic

I'll give them, say, 10-20k, and say "if you do this one i'll give 100k", so they double it and expect you to give them more to double, but instead you just walk off (scamming the scammers!) (although this isn't scamming)

Anyway, I myself have a few guidelines to doing this:
Make sure they're over a certain skill/cb level, otherwise they might think 10-20k is a lot and log from you just giving them that (wasting time)

9/10 times after they double your small amount they expect you to give the big amount after (whatever you do, NEVER give them any 'large money' (100k+) (unless you are filthy rich) this is usually when they will log out/ ignore you)

Anyway, I was doing this earlier on some busy worlds and gaining 1m+ an hour easy.

It's up to you to set the amounts to give to draw them in to expect you to give bigger amounts, but most of the time they will believe you (as most people actually DO give them large amounts after they do it once)

Anyway yeah.. I've just been having fun doing this over the past few days, if you're lazy like me then have a go, it doesn't require a lot of effort and is fun to watch ^^

ill give that a chance seems fun haha
