I tried just replenishing coins a little – it was faster than farming. It gave a boost at the very beginning: I was able to immediately take the necessary things on the trade and not waste time on boring grind runes. But I think if you have a lot of time, you can also get by farming, especially if you study what is currently dropping best.
For a quick start in PoE 2, it’s really worth paying attention to buying currency, especially if you do not want to spend hours on farming. Lootbar has a great section where you can safely and quickly buy PoE 2 Currency and the purchase process takes literally a couple of minutes. Ideal for those who want to immediately take the necessary items and focus on the gameplay itself.
