I started with an invest of 250 €. Mainly in SPS and DEC. I soon have seen, that I cannot compete with that and bought CL Packs in the General Sale.

Now I have a 5 digit investment in SPL. Because it hyped me later on.

I am not sure, how much invest is needed now in the start. But what is important is to balance the invest.

With the introduction of SPS staking requirements for rewards it is not enough to have a good deck. You also need the SPS. So for starters it is not the best idea to buy a strong deck and rise the ladder, without having SPS backing this.
