GTA 5 transfer money ps3?

I have been playing gta for a long time but I have no idea about the transmission system, I have a ps3 account of mine where a lot of money has been modded and how is that now when I log on to the ps4 I have everything (this is mine on the main ps3 account and it was randomly modded by one in the lobby)

No, on PS4 you have a completely new character with $ 0 and level 1.

No, this is not possible.

Is not possible, because there are different servers on the Ps4 than on the 3 Habs you try yourself, you just start from the beginning on the ps4
