f2p’s can only have upto 32 quest points, whereas only from 50 quest points and above your limit changes, so untill you are a member and do more quests your limit cannot increase

Yes it does jagex belives more experienced players should have more privilages and I have 19 quest points and i still have the 3k rule imposed on me. it is ment to keep people from trading items between accounts.

No, sorry, you need to be a member for quest points to matter.

I believe the limit goes up to 30k for members who do a lot of quests, but the limit is 3k for a f2p even if you do all f2p quests. This includes players who used to be members, and have a lot of quest points from that.

Also, it depends on who you’re trading with too. Both players must have high quest points to transfer 30k.

F2P the Limit is 3k

For a trade to be ‘balanced’, the total value of the items being given must be within 3,000gp of the items being received. For example you WOULD be allowed to trade an item worth 15,000gp for an item worth 17,000gp (because the DIFFERENCE is less than 3,000gp). You will be limited to a 3,000gp gain or loss every 15 minutes.

Here is a pretty good money making guide broken down by free players and member skills.

no, you need members to get a higher trade limit
and you need to do the quests to get a higher trade limit
