dragon stone method is best way
1.acc that needs money buys chaos or fire runes at Grand exchange
2.then Sell the chaos or fire rune to tzhaar rune shop to get 40k tokkul (1 chaos = 9 tokkul, 1 fire rune = 1 tokkul)
3. Have 20 intervory Slots open
4.acc with money sells 20 dragonstones to the gem shop
5.acc that needs money quickly buys the dragonstones from gem shop using the tokkuls
6.acc then banks the d stones and comes back with 20 intervory slots open.
7.then sell another 20 dragonstones to the gem shop
8.then repeat steps 4,5,6 and 7 until u get 50 d stones.
9. once u trade over 50 don’t sell anymore to the store because u have to wait 1 hr per 50 d stones u buy
each 50 d stones = 2.3m approx so repeat until u get as much money as u need
o btw the way i get 2 accs open is too open 2 internet pages, then make them small enough so i can see both runescape login buttons on each page. type in account info (username and pass) then when ur ready quickly press login on each page. thats the way i do it on a mac computer but there might be dif / easier way
o btw if u dont understand anything just send me a private message
