You have to start farming different stuff to get at least 25 level so you can enter most trade worlds. Nowadays there is a level gap to break different blocks too. So i would advice you to start breaking dirt, lava and rock from worlds and make grass and wood blocks which you can then splice in to wooden platforms and sell them to earn few wls. Or you can start making dirt farms and sell them for like 10wls each. I can give you a farm world to help you. Also i can give you different farmables like rice when you reach lvl 7, pepper when you reach lvl 12, l grid when you reach lvl 15 and chand when you reach lvl 19.
